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.

@chriskatanic8080 Год назад

@Kushagra Shrivastava All of the timers start at the same time, not one after the other. So the first logs to the console after 1 second, the second after 2 seconds, the third after 3 seconds, etc. This makes them print one second part from each other.

If we use const, you will find that his example prints 1 once, then throws an error. It is a constant and can not be changed after that, i.e. it is not a changeable “variable” in a true sense, so it is a misnomer.

@ashutoshguleria5968 Год назад

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 < 5; i++) { x(i); } This makes the function more dynamic.

@kirtikhohal3313 2 года назад

@sktwister14 3 года назад

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.

Thank you Akshay for making it simple to understand. I have one doubt: You have mentioned timeout to x*1000, so why every output like 1 2 3 ... is printing after exactly 1 second even if x is incrementing?

@agrawalmahesh616 2 года назад

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.

@surenderoati 2 года назад

Because, Only the inner function part is put somewhere else not the whole setTimeout function. Akshay sir, please correct me if i am wrong.

@MrudulSankhere 2 года назад

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?

Awesome! A small quiz: "closures keep reference not the actual value" (repeat it 10 times) and guess the output of below snippet for(var i=1; i { console.log(i); i = i + 1; }, i*1000); } console.log("outside: ", i) if( i < 10 ) i = 10;

outside:6 // The for loop get executed before the setTimeout func 10 11 12 13 14 //after the for loop execution now the " i " value become 10 and the value in settimeout has the value 10 beacuse of lexical scope .

I would have watch this video earlier.. Everytime when I was attending the the closure concept was appearing in the question list and everytime I confused a lot even I read I remember the code without understanding.. Thank you!
