Thank you so much sir. I wish I had a teacher like you in college.

Thank you for a nice compliment. I believe teachers job is to break down harder concepts into smaller simpler pieces so that students can understand. Its very much like how mothers do it to the food which is harder to digest as a whole. Unfortunately only few of my teachers did that.

Hi. Your videos are awesome. Especially the earlier videos on creating objects helped me a lot when I started OOP. Can you, sometime in the future, make a video on difference between the new ES6 class (extends) and creating new object instance using new(). Thank you :)

Yes that is under my radar. I will try to make it next. Thanks for watching :)

Thanks a lot for these tutorials. Is there is a place where we could suggest the topics for you to cover for future videos? If you don't mind, of course. You were mentioning in some of your videos that people can hit you up on email for any questions, but you never leave it in the description.

@Techsithtube 7 жыл бұрын

Either you can leave me a message here. or On the main channel message thread. Most of the people suggest topic in their comment. Actually , this particular video on setTimeout was suggested by a viewer via comment.

thanks for your precious time for all your tutorial please make a video on synchronous for each loop in es6 where each loop does a heavy task let say API call and pushes the result in a array and console log the final result array once all are done

@Techsithtube 7 жыл бұрын

Do you mean asynchronous or synchronous ?

@akhanda- 7 жыл бұрын

techsith sry asynchronously but the final console should be only after the foreach loop ends

@Atif1702 6 жыл бұрын

Thanks. One question: You said "setTimeout is not part of main JS engine but it is part of Web API", what is the difference between the two?

@Techsithtube 6 жыл бұрын

JavaScrit as a pure language is the main JS engine like V8 engine by google. which you can take and use is on the server side as node. Anything else that browser need that is a separate API called Web API.

@Atif1702 6 жыл бұрын

Thanks once again, it is so kind of you. I googled the rest to get a better understanding. But please make videos on these two topics as they are rarely found on web. 1. "JS Engine, JS Runtime Environment, Node.js. What are these and what is the difference between these?" 2. "Stack, Heap, Execution and call stack, Queues, Event loop. Where do they exist actually and what do they do?"

can you make a video of constructor classes on javascript to create multiple items in a screen ? im trying to make a game creating multiple items dropping from top to bottom. the sooner the better or can u point me out to a video i can reference.

Are you writing in pure javaScript?

Sir when i click a link then url is autoupdated with id i mentioned with href .and I am doing replaceState("state",null,"urlmodified") .then still #anchor is shown but setTimeout(callback,0)solves problem.why does so

@Techsithtube 4 жыл бұрын

its because you are calling asynchronous code. so the update is not happening right away. waiting for it solves it.

I think you borrowed some functionality from jQuery for $(#...).click() eventlisteners to be used with that syntax. Can you please explain this part in a more clear way. Generally in pure JavaScript we use addEventListener() function after grabbing the relavent html element.. Using $ is somewhat syntactic sugar borrowed through jQuery. I am curious to know which code fragment in jQuery made this possible.

@Techsithtube 5 жыл бұрын

Yes i am using Jquery $() in that example, actually I added jquery library to this project so that made it possible. Every code playground has feature to add most commonly used JS lib. there is actually a drop down in the playground i am using to select a JavaScript lib. with pure JS we use addEventListnere() however, since Jquery makes code simpler and most people know Jquery I use it here.

What is event loop

@Techsithtube 5 жыл бұрын

Event loop is how javaScript decides what to execute next.

what's the difference between let and var? (PS:- Im a newbie :-) )

@MrRuchir23 7 жыл бұрын

let is introduced into ES6 and with it variable difined has a block scope Eg. { let a=20; var b=10; } console.log(a) // undefined Console.log(b)//10

ruchir saxena Thank you mate ☺.

also adding to @rushir example there is no hoisting . I have a tutorial on this you can check it out. I relesed it few weeks a go called " Hoisting and scoping issues with var" { console.log(a) // error Console.log(b)//undefined let a=20; var b=10; }

@wol2231 7 жыл бұрын

techsith sure

@osazemeusen1091 6 жыл бұрын

hoisting is how the js interpreter understands your code. this could make your some variables in your code be undefined and could cause some issues when your code runs. always use 'use strict' and declare your variables at the top to avoid any issues.
