Great job Akshay, I am myself a javascript developer and love JavaScript, u really inspiring, doing a grt job not only in educating them but explaining them these tough concepts so that even kindergarten child can understand, really amazed to see your passion . God Bless you.

After reading many articles and watching other videos about closures & loops, I finally understand why we experience this behaviour. The key was to understand that the async function stores the reference and not the value! Thank you, and I love your style of teaching.

You are amazing as always brother . Nobody understands the hard work you have done off screen , referring so many resources and books , making masterpiece videos are also challenging and time consuming. Completed Season 1 play list . switching gear to season 2 .

Javascript is tricky but your explanation is so crisp and clear that even a non JS developer can understand it.

The whole Namaste JS series feels like dope and the meme at the end of this video just mimics that!!! Hats off to you Akshay.

got that answer of setTimout running in loop before you printed on console. Very cool example of closures. Seriously man best playlist on JS on youtube.

I always thought that only C++ template spaghetti has something mind bending to offer, but now I have a purpose to learn JS. Thank you Akshay bhai!

Interviewer asked me exactly this question, but i didn't know. But thanks to the knowlege i got from your other videos, i was able to convince them to hire me. Thank you Akshay, for everything you've done and everything you'll be doing in the future. World needs more people like you, who not only are successful themselves but also guiding others and making their journey a lot easier.

I was already aware of the question and output but didn't know how to fix this problem. You explained it very beautifully

Things learned: 1. setTimeout stores the function in a different place and attached a timer to it, when the timer is finished it rejoins the call stack and executed. 2. Without closure the var reference gives the latest value as it does not retain the original value but rather has the reference so any update in value after timeout will be shown. 3. If we use let/const because they have block scope, every time a new copy of variable is attached, thus this can be done without closure.

I got so excited when I saw this because I stumbled upon this exact problem some time back while I was working on a sorting visualizer project and couldn't figure out what was wrong with my code for days. Ultimately someone advised me to use async and await but now i fully understand why that didn't work.

For those having dfficulty like me in understanding why each iteration creates its own closure or stores i in a separate memory space unlike var. You can think of each iteration of for-loop like a mini function almost, with new/different value of i (1,2,3,4,5) and and since let is block scoped (block scope meaning within the curly braces of each mini-function) it stores reference to i at different place (different closure made by different mini-functions). Also that, a closure closes over or captures the current scope when the callback function is passed to setTimeout.. But why does it closes over when call back function is called? Because a closure is formed when a function is created inside another function and the inner function has access to the outer function's variables and parameters.

One more way to solve that problem: function x(i) { var a = i; setTimeout(() => {console.log(a);}, a * 1000); } for (var i = 0; i x(i); } This makes the function more dynamic.

@agrawalmahesh616

2 жыл бұрын

when the settimeout was executed in the current execution, at that time the value passed to the settimeout function was 1000, 2000 and so on. so based on that value the timer is confugured in the background thread. when the variable is used to manipulate, it gives output as single value which is 1000, 2000 etc. you are not keeping reference of that variable. thats why it was printing aftet 1, 2, 3 seconds.

Awesome Video. I love the way of your teachings. You're enjoying Man😀

Why does it create a new copy when we are using let? In every loop iteration the variable i remains the same, it is just that its value increases and is stored at the same place. Why is setTimeout unable to access just the reference to i variable and behave the same as var? Why is there a new copy associated? I did not understand why it happens just because it is block scoped. The timeout function will always have "let i" with it since it is always present in its lexical env just like a var variable.

Hi Akshay, Thanks for the last example I was literally scraching my head because this question have been asked to me by most of the interviewers and I got answers online but couldn't understand. But now thanks to you.

I love your energy! Thanks for the great explanation.

First of all, beautiful series. Amazing work giving the in-depth knowledge of JS Concepts. Thank You very much. Question: In the block of for loop when loop variable is declared using 'let', you mentioned that in each iteration, a new copy for variable i is created. i++ executes by going to the reference of the variable and then adding 1 to it. I want to understand when the new reference is created? after i++ executes and it enters the for loop? Or when the loop body ends? Also, is there a separate instance in this case just adding to the value of i and creating a new instance with the corresponding value in that loop? Basically, I understand that in each iteration a new memory address is assigned. I don't understand when this process of creating new reference executes. 1. loop body ends, new reference created, old memory freed, i++ executes? OR 2. i++ executes, new reference created with updated value, old memory freed, loop body starts? Which of these is the correct order?
