JavaScript is a dynamically typed language, which means that data types of variables are determined by the value they hold at runtime and can change throughout the program as we assign different values to them.

First time i saw any tutorial from this man. He is truly a Gem❤ 9hours of pure knowledge, best tutorial on UA-cam for beginners. he will clear all your doubts. Thanks alot sir!! Huge Respect from Pakistan.
10: 34 pm 1st November 2023 I have completed a 9-hour-long course on JavaScript ✌:) Thank you for this valuable series. I appreciate your efforts, sir.
Your web series for JS is very helpful. I've watched many UA-cam JavaScript courses, but because I'm new to this field, I couldn't understand them well. Your teaching style is great, and I hope you'll keep teaching. Your explanations really help me learn.

This is the best ,complete ,most logical,most meaningful one shot ever i have seen in javascript . hatttts of to sirr for hardwork and dedication for students on youtube they are doing their best to provide us with the most complete series without a payment !!!!! shared with friends too uh deserve millions more viewss all the best sirr!!!!!
This channel deserves 1m+ subscribers. The way sir teaches the concepts is Mind-blowing . From now onwards ,this channel will be my first preference in terms of coding .🤴🤴🤴🤴🤴🤴🤴🤴
Love for hindi ❤ . 3 days me part 1 complete hogya without feeling stressed or overwhelmed. A lots of information explained in intersting way always makes learning fun. Thankyou hitesh sir for your efforts. Hindi me coding is my personal favorite now..
A quick tip for those who are using for in loop for arrays. remember that the key used for (const key in arr) here is a string so if u want to do some operations on that key thinking its a number that is not possible. Why is the key a string you would ask that is because its being used for an object and object takes strings as keys. For example: const sum = function (arr) { for (let i in arr) { // since i is a string so we need to convert it to a number with parseInt method i = parseInt(i, 10); if(i < arr.length-1) { arr[ i ] = arr[ i ] + arr[ i+1 ]; } } return arr; } console.log(sum(arr)); This will print an array with elements that have sum of adjacent element.

Hitesh sir, you are a wonderful teacher. I must say teaching is an art and you are one of the best in this field. I have completed "Javascript in 1 shot in Hindi | part 1" and felt somehow confident now. Many thanks to you. I will start "Javascript in 1 shot in Hindi | part 2" very soon. Wish you good luck, please bring many more videos in the future. One request please add more JS interview questions.
I have watched Javascript series from Thapa , codewithHarry and........ But the level of content this series have is on another level. Thanks Hitesh sir for the wonderfull series to explain all the things related to JS . Thanks from the depth of my heart ❤❤❤❤
hi bro , i made 2 videos about dsa with javascript , i hope that you will be interested 😇 , currently i am making a video on Linked list , but i need some feedback... , ii just want to know your Hones opinion , do you think those videos are made well?
Finally Done Completely took me 3 days since i already knew JavaScript but wasn't confident enough , this time made Notes as well Thanks Hitesh Sir . I will start the 2nd Part now excited to Learn DOM and Async JS
Bhayya don't add ur old videos here currently running js series is running well and excellent & people will not be able to stick one series and you lose the subscriber as will, keep here only new content ❤❤ from Hyderabad..
I really like your confident style of teaching, Whenever i have to learn any web dev concept I would go for your content. I really appreciate your all the hard work you have put in for creating this amazing course. Sending you lots of love from Pakistan ❤
"Thank you so much for sharing such amazing teaching and knowledge! Your content is truly inspiring and has made a huge difference in my learning journey. Keep up the fantastic work-you're changing lives one video at a time! 🙌🎉"
Started yesterday! Being a final year student its very important to clear basics for interview purpose and to build something. Your video has been a life-saver for me! Being a chai-lover, I always keep my chai ready before coding and so do you while teaching. You are really a good teacher, its always quality over quantity of videos for you. Cheers!
Just finished. Wonderful video. Wish I had such a tutorial 10 years back. Much appreciated for all the effort in making the entire series so easy to understand.
took me 6 day complete it ,I would like to say this is the one of the best js tutorial I came across on yt thank u so much hitesh sir for your efforts💓
Is this for real ? Such a perfectionist in all aspects , the way u speak , the way present , the way u teach .....impressed in all aspects of your perfection. Keep doing this work ❤
Thank you so much, sir, for these videos. I didn't have any confidence in JavaScript before, but now, confidence is building up. Your tutorials have been incredibly helpful, and I appreciate the effort you put into making complex concepts easier to understand.

Here is the revised text: Primitive Data Type (Call by Value) => 7 types: String, Number, Boolean, null, undefined, Symbol, BigInt. 1) The data type of null is an object. 2) The data type of String is a string. 3) The data type of Boolean is Boolean. 4) The data type of Undefined is undefined. 5) The data type of Symbol is a symbol. 6) The data type of Number is number. 7) The data type of BigInt is BigInt. And the Data Types of Non primitive data type is Function object. Thank you so much sir I am grateful for your effort to give us the valuable source of learning.

JavaScript is a dynamically typed language, which means that data types of variables are determined by the value they hold at runtime and can change throughout the program as we assign different values to them.
watching video one more time revison bhi jaruri he 😊😊😊😊
The best thing about this channel is He explains everything in detail and in a very calm and composed way!
Yes, Indeed this video is so far the best I have seen.

Thanks Sir for giving this video
You are most welcome
Your web series for JS is very helpful. I've watched many UA-cam JavaScript courses, but because I'm new to this field, I couldn't understand them well. Your teaching style is great, and I hope you'll keep teaching. Your explanations really help me learn.

Thank you alot, you are blessing for us ❤
Part 1 Completed (13/01/2024)
A quick tip for those who are using for in loop for arrays.
remember that the key used for (const key in arr) here is a string so if u want to do some operations on that key thinking its a number that is not possible.
Why is the key a string you would ask that is because its being used for an object and object takes strings as keys.
For example:
const sum = function (arr) {
for (let i in arr) {
// since i is a string so we need to convert it to a number with parseInt method
i = parseInt(i, 10);
if(i < arr.length-1) {
arr[ i ] = arr[ i ] + arr[ i+1 ];
}
}
return arr;
}
console.log(sum(arr)); This will print an array with elements that have sum of adjacent element.
