What is the value referred to when we assign the setTimeout function to a variable?

Question

Hi when I assign the simple setTimeOut() function to a variable and console the variable, it produces some integer value as below:

So, I want clarification on what the value denotes. The value is changing when I try the same again. So please provide me an explanation of the value we get while assigning the setTimeOut() to a variable.

Answer 1

The setTimeout function returns a unique id with which you can stop your setTimeout like this clearTimeout(timeoutID) . It's the same with setInterval .

Answer 2

The function setTimeout() returns an identifier that you can use to prevent the execution of the function by calling clearTimeout()

Answer 3

It is id returned from setTimeout() which used to clear the timeout

myTimeout = setTimeout(function, milliseconds);
clearTimeout(myTimeout);
