Ever wondered how does JavaScript sorts the array when you call `Array.sort()` ?

Well It all depends on the runtime engine of the browser.

for example,

- Chrome uses V8 engine, which is a JavaScript engine written in c++. As per their documentation
  [V8](https://v8.dev) is Google’s open source high-performance JavaScript and WebAssembly engine, written in C++. It is used in Chrome and in Node.js, among others. It implements ECMAScript and WebAssembly, and runs on Windows 7 or later, macOS 10.12+, and Linux systems that use x64, IA-32, ARM, or MIPS processors. V8 can run standalone, or can be embedded into any C++ application.

- Firefox uses SpiderMonkey engine, which is a JavaScript engine written in C++. As per their documentation
  [SpiderMonkey](https://spidermonkey.dev) is Mozilla’s JavaScript and WebAssembly Engine, used in Firefox, Servo and various other projects. It is written in C++, Rust and JavaScript. You can embed it into C++ and Rust projects, and it can be run as a stand-alone shell.

- Safari uses JSC engine, which is a JavaScript engine written in C++. As per their documentation
  [JSC](https://webkit.org/) WebKit is the web browser engine used by Safari, Mail, App Store, and many other apps on macOS, iOS, and Linux.

- Microsoft Edge uses Chakra engine, which is a JavaScript engine written in C. As per their documentation
  [ChakraCore](https://github.com/chakra-core/ChakraCore) is a JavaScript engine with a C API you can use to add support for JavaScript to any C or C compatible project. It can be compiled for x64 processors on Linux macOS and Windows. And x86 and ARM for Windows only. It is a future goal to support x86 and ARM processors on Linux and ARM on macOS.

We will take the 2 most popular browsers as reference, and compare the performance of `Array.sort()` in each of them.

- ## Google Chrome

  Since v8 engine Chrome has been using TimSort algorithm for sorting the array.

  ![avatar](https://www.openbookproject.net/books/bpp4awd/_static/ch10/timpeters.jpg)

  TimSort developed by <u>Tim Peters</u> in 2002 for [python](https://github.com/python/cpython/blob/main/Objects/listsort.txt).
  While Mergesort usually works in recursive fashion, Timsort works iteratively.

  The Array is divided into Run blocks.
  These runs are sorted using insertion sort one at a time, and they are then combined using the combine function from merge sort.
  The Array is sorted solely using Insertion Sort if its size is smaller than run block.
  Depending on the size of the array, the run's size can range from 32 to 64.

## Algorithm:

1. Divide the array into the number of blocks known as run.
2. Consider the size of run, either 32 or 64 (32 is the default).<br/>
3. Sort the individual elements of every run one by one using insertion sort.
4. Merge the sorted runs one by one using the merge function of merge sort.
5. Double the size of merged sub-arrays after every iteration.

WKT the basic operation of insertion sort is Comparing.

When we merge the sorted lists, we come up with a total n-1
comparison because the last element which is left will need to be copied down in the combined list,
 and there will be no comparison.


Analyzing Array.sort() & measuring the performance in JavaScript


So a Little intro to Typescript, It was developed by Microsoft as a opensource project and its now also maintained by Microsoft.

So Basically in a nutshell Typescript is the super set of JavaScript meaning any valid JavaScript code is a valid Type-Script Code.

If you have experience with JS you know that the data type is completely dynamic, to give you a example, I declare `arr` as a const , and try to apply `arr.map()` function, This is a error because `arr` is not a array to map through and we’ll get to know this error during run (JS doesn’t need any compiling we can directly run / interpret it in Browser) time which is more frustrating for a developer

Now, lets come to typescript you have to mention the datatype of `arr` which is a string and if you try to apply `arr.map()` the text editor will scream at you saying that you cannot loop though a string….

TypeScript is strictly better than JavaScript. Some of the advantages are below,

* Static types prevent an entire category of errors. And they prevent the errors before you even save the code to disk. The sooner you detect an error, the cheaper it is to fix in developers point of view.

* It forces you to write clean code, so if you forget your code after a couple months you can just see what you have written and what does this do in just couple minutes..

* If you are building a large Systems, Its Oriented and complex systems is no longer a nightmare.

## Compilation

A main dIffrence between JavaScript and TypeScript is compilation. There is no need to build JS code. In the browser, it is interpreted and executed. TypeScript code, on the other hand, must be converted into standard JS and then compiled. It may seems that you might be wasting time, but you are actually saving time. Compiling the code takes a few extra seconds, but it saves time when you are testing your application.

After everything is said and done, both Typescript and JavaScript have their own set of limitations and features. JS is a dynamic and lightweight coding language designed to improve HTML web pages. It is not, however, a full-fledged scripting language. JS is an interpreted programming language that runs in the context of a web browser.

Typescript is compiled to JS, which can be used in any JS code; as a result, Typescript has more advantages, making it more significant and popular.

## Final Notes:

The community for Typescript is not big as JS

Use TS always whenever you are making a big application with complicated Data and interacting with various Databases

You can get more accurate Auto completions in your text editor as the transpiler knows what data type it is

Start Migrating your codebases to TS, its easy just renaming the file extensions to .ts` Of course, JavaScript code won’t become a strict TypeScript automatically. It still takes some time and effort to convert.But its so much worth it to make it.

Just use Ts, You’ll thank me later xD.



Why I Prefer Type-Script more than JavaScript …?

On March 23rd they declared it as a national Lock-down in India, many people freaked out some of them even left the city which had fed them their entire life, some of them pulled their wrists and helped society.

![LockDown Image](https://miro.medium.com/max/700/0*jBgDKoR0AKa5R-_u)

The academic institutions started to teach in online platforms, Now here lies the problem: how can you expect every student to have a stable internet connection and an electronic device to attend moreover the institutions made online classes mandatory to attend them. (This is a talk for another time)

Now I want to talk about the problems faced by Deaf people

How can a deaf student listen to the online classes where they themselves can’t understand the lectures in offline classes?

Deaf students face many problems in listening in the class because they should pay attention to the lip of the professor to read lip

After all you might think several students wear glasses and need no further assistance same happens with deaf students, But hearing loss is more complicated than that.

### I want to clear up some common misconceptions about the Hearing-Aid

This is really a common mis-understanding that hearing aids are just like Glassses, that they enable the person to attain 100% clear vision.

**NO a Big No!!!**

Hearing aids just amplify the the sound received, doesn’t improve the clarity of the sound.

A person might still struggle to understand others even when wearing the Hearing aids, They struggle more now with the masks on (Covid-19) because the person sees the lip movement and try to hear at the same time.

I will explain why a Deaf Person trys to read the Lip:

Imagine that You are Deaf now, You don’t know how a couple words are pronounced, ex: mississippi (classic permutation problem xD)

I will try to speak mississippi to you with the mask on , The Persons hearing aid catch it as misipi, this seems like a new word to you, You Fail to understand what is this word, But when you try to read the lip and listen to the word you might understand it clearly.

We can understand some of the common words like, appa, uta, college, computer, why ?

Because these are the words which we speak Daily, Basically mind is just like Machine Learning, It constantly learns itself by how this word is pronounced, etc…

Listening is a tough task. Hearing loss makes it extremely difficult to hear some speech sounds. Speech sounds are lost in greater numbers as hearing loss is more. Your brain has to constantly understand what someone is saying when you can’t hear particular words/sounds. To interpret what originally sounds like gibberish into recognizable speech, your brain must mentally fill in the blanks, adding missing speech sounds and guessing at unheard words. This requires a high level of focus on the part of the listener. This level of focus exhausts mental resources quickly, leaving the listener exhausted. When all of their mental energy is focused toward grasping what is being said, there are few resources left to truly retain what is being said. As a result, the person may/may not understand what he or she had been telling.

Also we cannot neglet background noises; Hell , A normal person can’t even hear properly in noisy background.Background noise can amplify the struggle to hear.

Lipreading requires a significant amount of mental effort and concentration. People who are deaf or hard of hearing do not instinctively know how to lipread, which is actually a popular belief. It’s an acquired skill that takes years to perfect. Lipreading may be more challenging for people who lost their hearing later in life compared to those who have been deaf or hard of hearing since childhood. Because of the speaker, lipreading can be difficult or impossible. Lips can be difficult to read if you have facial hair. When a speaker makes exaggerated lip movements or doesn’t move their mouth much when speaking, it can be difficult to read their lips. Many sounds are also made in the back of the throat and are not visible on the lips. Lipreading is only possible for 30–45 percent of voice sounds. via (<https://www.huffpost.com/entry/lip-reading-is-no-simple-task_b_9526300>)

Combine all of the above problems with writing notes, it seems like it is a impossible job.

In India the Sign Language is considered as a Taboo, what the people don’t understand is it is a way of expressing the feelings by a person, The people talk like it is a disgrace to the humanity, which hurts the Feelings.

When I planned to write this, I decided do some research, I was shocked to learn that only around two percent of deaf children in India attend school, further perpetuating a culture of illiteracy and low economic opportunity.

Despite a massive audience in India, closed-captioning on television has lagged. Adult lack of education has delayed efforts to extend these services to the wider population, in addition to the lack of investment in technology.

**I tried to give a small insight to the Problems faced by the Deaf Person**, there are so many other un-parallel problems which cannot by penned down. Now enough about problems, Lets look at some of the People who have tried to overcome the challenges,

- Shruthi
  
  Shruthi is originally from Shivamogga, Karnataka. She had severe to profound hearing loss in both ears and was fitted with hearing aids. She shifted to Mysore and joined the school run by the Parent’s Association of Deaf children (PADC) after hearing news about the school from her grandfather when she was aged about 2.5 years. Initially, she was trained in her mother tongue Kannada for 3 years in the school. Thereafter she got admitted to 1st standard in a regular mainstream school and studied in Kannada medium till 7th standard and later changed the medium of instruction to English. She excelled in her studies and was able to secure a good rank in CET and got admitted to engineering in SJCE Mysore in Electronics and Communication. She eventually graduated from SJCE (8.98 credit points) and got selected to Wipro in a campus interview. Currently, she is working in Wipro Technologies, Bengaluru as a Senior Software Engineer

- Kavitha
  
  Kavitha has severe loss in the right ear and profound loss in the left ear. She was fitted with bilateral hearing aids. Kavitha joined a preschool run by the Parent’s Association of Deaf Children, Mysore at the age of three and a half years. She underwent intensive training in the Preschool for 3 years. Subsequently she joined regular school in Mysore. She studied in Kannada medium till 4th Standard and later changed her medium of instruction to English. She completed her SSLC with distinction by scoring 80% marks. Later she joined a Polytechnic and completed her Diploma in Computer Science with distinction. Also she did her BCA through Distance education from Karnataka State Open University, Mysore. During her school and college days she had participated in various competitions and had bagged many prizes. At present she is working in WIPRO, Bangalore as a Software Engineer. She is married and has a one year old daughter. Even with many obstacles Kavitha was able to overcome them and came out with flying colors.

- Mahanth Bagi

  Mahanth hails from Belagavi, Karnataka. He was diagnosed with Severe to Profound hearing loss in both the ears and was fitted with hearing aids when he was 3 years of age. Initially he received pre-school training in his mother tongue Kannada for 3 years. Later he was trained in English. After successfully completing his preschool training he studied in a regular school in Belagavi. He cleared his SSLC and PUC examinations with distinction from a regular school and college. He took up the CET entrance examination conducted by the CET Board of Karnataka and came out successful. At present he is studying in 2nd Year MBBS in Mysore Medical College, Mysore

_there are so many people, I will try to post a collection of 3–5 people in comming articles._

Also a important point that I want to point out is each persons learning experience is different
> “Just because you’ve met one deaf person , doesn’t mean you’ve met any deaf person. You cannot generalize anyone and their experiences.”

Also if you are free read [this](https://medium.com/age-of-awareness/virtual-deaf-and-hard-of-hearing-education-f78e31c98f00).

So long….


The Problem which no one Overlooks


Today I went to eat Davanagere Benne Dose, As it had been a long time, I ate Benne. Dose and the weather was appetizing to eat a hot burnt crispy Dose.

I took my Activa and went to my regular Dvg-Benne- Dose, I know the taste of Original Davanagere Benne. Dose is irreplaceable in Bengaluru. But this. Dose’s taste was the closest to the Original Davangere Benne. Dose.

But now, I am not talking about the taste Comparison, It is a Talk for another time.

To give you a small description about the hotel, It is almost 5 ft Wide and is around 25ft long, Basically a small Hotel. It is being run by a couple from North Karnataka. They have 2 children as well.

When I was devouring the scrumptious Benne Dose, I observed that slippers of the owners were placed outside, I asked them why ? This is what they told me,

```
Sir, Naavu ond hattu (10) varsha aytu Bengaluruige bandu,naanu matte nam maneyavaru bandvi,Bandaga naan hattira bari 1000 maatra ittu, naanu yeneno kelsa maadi swlpa duddu save maadi ee hotel na sumaru 5–6 years back open madideve, Ivattu nan makkalu Olle Schoolge hogta idare,nan hatira ond hosa gaadi ide, Idella ide hotelinda agiddu sir, Naavu dina ee hotel ge pooje madtivi, Devasthanakke Chappali hakond ollege hogbardu anta heltare alva, namge ide devasthana,Uta mane, batte yella kottide
```

### Translation
```
Sir, It has been around 10 years, Since we came to Bengaluru.When me and my wife came here I had only 1000 rupees in my hand, I worked some odd jobs and saved enough money to open this hotel back in 5–6 years, Since then my life has been going good, My children are studying in a Good School, I was able to purchase a new vehicle.
It is a proverb saying that We musn’t wear Footwears inside the temple, For us this hotel is the temple, It has given us Food, Home to live, Clothes to wear. We respect the hotel as much as we can..
```
I was awestruck listening, WOW they have somuch respect to a building.

We Indians worship even small thing if we belive enough in them.

It’s so beautiful to observe such small things in our lives.

> God’s supreme word to us is life; our highest worship of Him is love for the living.

Monika Halan is Consulting Editor with Mint, India's second-largest business daily and a well-known media personality. Monika is the author of the best-selling book Let's Talk Money published by Harper Collins in 2018. She has worked across several media organizations in India and has run many successful TV series around personal finance advice in NDTV, Zee, and Bloomberg.

She is a regular speaker on financial literacy, regulation, inclusion and consumer issues in retail finance.

**My Opinion**:

Do you know why most sports athletes go broke just after few years of retiring ? They almost retire with 250% more than the net worth of a common man. still go broke. The main reason Is Poor Finance Planning!!

They wish to Royally like they used to leave when they were playing, what they forget is they don't have a passive income now!

If you are Someone who almost spends all of the money you have then this book is for you.This book shows how to manage finance, and make money work for you, ie; Passive income..

A famous quote :

> "Don’t let money run your life. Let money help you run your life better."- John Rampton

Our choice of college, company and career are often determined by the amount of money at stake. Throughout our life, whether it's to celebrate our big moments or deal with emergencies, money is a big consideration in the decision-making process.

Yet, we are hardly ever taught about making money work for us. Let's Talk Money is the book that demystifies the world of personal finance and investing for the beginner. This helps us to start viewing the money in those accounts differently.

Now in many homes, they think that investing in Stock MArket is like gambling, but if you have invested analytically and carefully that money can double too, if not that money can be lost too…

Later, the author introduces the concept of the ‘money box’ as the cornerstone for our financial life. These include parking all the money in low interest-earning products such as Fixed deposits, not doing enough due diligence while buying health or life insurance, considering real estate as the best return on investment, seeing equities investment as a short-term quick rich scheme etc...

The things that made this book stand out for me are

Easy narration style helps demystify the different financial products. This can act as a useful guide when you are buying any financial product such as medical cover, life insurance or mutual fund. Provides a structured way to invest according to our goals and ultimately move towards financial independence. This book is a must-read for someone looking to get started on their financial journey.

I recommend reading this book for almost every college student before graduation so that you can get an idea How to manage your finance.

You must have heard about Image Processing. Well, what is it?

Image-Processing is processing each pixel of data present in the image, Now don’t tell me you haven’t learned the term PIXEl, if you haven’t here it is, then pixel represents the smallest possible element in an image. Several pixels contribute to a complete image.

open-cv (Open Source Computer Library) an open source pre-trained module which was started in 1999 and written in c++, but the recent Algorithms are being written in Python and Java.

Now we are going to learn about the most basic operation in open-cv, which is reading the image.

### Steps:

open a new folder in terminal and initialize virtual environment:

```virtualenv env```

then activate the virtual environment by:

```source env/bin/activate```

install numpy and matplotlib

```pip install numpy```

```pip install matplotlib```

Install OpenCV via pip

```pip install opencv-python```

or install by conda env

```conda install opencv-python```

or if you are a Linux user like me,

```sudo apt install opencv-python```

* Reading an image is basically feeding the image data to the computer, after installing all of the above modules then save a random image in your file.

Then copy the image file path

#### Code Snippet

```python

import cv2 # we are importing the cv2 module from opencv


image_path = '/home/prajwal/OpenCv/image_1.jpeg' #change this path by your image path

image = cv2.imread(image_path) # Reading of image

cv2.imshow('Image-Reading', image) # Image output in new Window

cv2.waitKey(0)

cv2.destroyAllWindows()
```
A window with the image and Title "Image-Reading" will pop out
How easy was that, You can do so much more with the opencv? Follow this space regularly to know them.

##### Thank you.


Introduction to Open-Cv


**F\*\*\*** this Covid, I thought to myself, having cursed the pandemic countless times. This time wasn’t that much different. If it wasn’t for the pandemic, I would have had a blissful college life. After finishing my CIE-3, I was thinking of writing the improvement CIE, I sat in my room looking over my “to-do list” which comprised Experiential Learning-Phase 2, English Essay, and lastly CAED submission. I glanced over the deadlines, the English one was due tomorrow so I started to write it. The deeper I went to writing, the more lost I was.

I kept thinking about this cursed pandemic. Well, I’m not the only person who is facing difficulties. Many people are facing problems, and if we look from the perspective of those people, we would feel lucky for not having those problems.

Have you ever seen a child staring at an empty glass cup imagining that his dad would pick him now and play with him? But unfortunately, as he was a COVID-19 ambulance driver he had worked intensely during the lockdown, but The Covid-19 didn’t leave him too, he was affected by the virus and he died.

![covid_croud](https://miro.medium.com/max/700/0*yLsSgVnuYumLZcrV)

Can you imagine that child’s pain, sorrow, the devastating look in his eyes, the cold hand waiting to be warmed by hugging someone close to him but there is no one, not even his mother, he had lost his mother because of premature birth now the only thing he used to hug was also disappeared.

As cold as this sounds, he might be one of the luckiest ones to be born during this era where people have a shot of living even if they get sick. We have been through a countless number of wars because of some trivial misunderstanding and someone’s ego not being able to take that. As clumsy as this sounds, we are still here at this moment. That’s why my favourite quote is “Yesterday was the past, Tomorrow is the future, But today, My friend is the present! That’s why today is called a gift”

You are still here, you shouldn’t exist. Yet you are, so let me say it clearly without a doubt, you are a miracle.

A wise man once said, 
> “Our daily lives we spend like this, might just be a series of miracles.” Our existence is so obvious that we take them for granted. That doesn’t change the fact that we shouldn’t be existing right now… it’d take the faintest miracle to be here.”

While imagining these I was suddenly questioning myself, _Why do I exist?_

Well, I’m still looking for an answer.

Shit! My English essay submission is tomorrow I gotta go bye 👋

Hope Y’all had a pleasant read.


How Lucky Are We……?

Robert Kiyosaki

Kiyosaki is best known for his book Rich Dad, Poor Dad, the #1 New York Times bestseller. Kiyosaki followed with Rich Dad’s CASHFLOW Quadrant and Rich Dad’s Guide to Investing. He has now had at least a dozen books published. A partial list of his books is included below.

**My Opinion**:

When I started to read this book, I thought The cover page has authors photo, I was judgemental about this book. I think I was right in some way because he makes real estate sound so easy where it is not so easy. So, while this book gives you such excellent advice as “learn from failure”, “make profitable deals”, and “work hard for yourself”, it doesn’t actually give you a system or method to make money.

He started to make counterfeit money with a goal to become rich at the age of 9 indeed we can say that he had a great mindset. But this book tells you that you have to learn financial management. where ASSETS are required and LIABILITIES must be avoided. (repeatedly)

This book is clearly directed towards the people who are not smart enough to realize that they should ‘work hard and not give up’ if they want to succeed, but who are smart enough to be able to figure all the rest of the logistics out by themselves.

It encourages you to invest in real estate, and there if you make a loss it teaches how to be not sad about losing the money instead of taking it as a lesson for future investments. It gives you simple explanations of how money works. It will not give you any trading tips, but it helps you understand the things no one teaches us in the school or at home. The financial insights aid you to take action, and be your boss.

Sudha Murty

Smt.Sudha Murty was born in 1950 in Shiggon north Karnataka, she did her B.tech in BVB college of engineering specialized in Electronics and electricals. She got her masters in IISC Bengaluru. now she is the chairperson of the INFOSYS Foundation. She is a prolific, excellent writer. Some of her books consist of, Dollar bahu, Mahashweta, The old man and his god. etc…
Smt. Sudha Murty was the recipient of the R.K.Narayan award for literature and the Padma Shri in 2006 and the attimabbe award by the Government of Karnataka.

**My Opinion**:

Three Thousand Stitches a heartwarming, soothing collection of 11 short inspiring stories of Sudha Murty’s life. time flies when you are reading this book.

Two decades ago when she tried to make changes in the DEVDASIS’S life they threw chappals at her, when she went for the second time they threw tomatoes at her instead of taking this as a strict no she took this incident as an improvement from chappal to tomatoes. then she changes her approach, perseveres, and earns the trust of the Devadasis. Slowly, and surely the changes occur at the grassroots. The women march towards a sense of financial independence by starting a bank and send the children to be educated. That was the mindset Sudha Murty had. Like this, she has shown her various courageous, powerful, inspiring short stories in her book called Three Thousand Stitches.

The highlight of this inspiring story is the straight-from-the-heart storytelling style of Sudha Murty. No attempt at weaving together complex and pretentious sentences. Just simple and effective storytelling! I love this! Must read her other books!
