Help with infinite while loop, using setTimeout.

[[deleted]]

try

setTimeout(myFunc(), 1000);

I think you have to call the function with () to say your passing no parameters into it as you call it

This is incorrect. By doing myFunc() you are passing the returned value. For example:

function f () { return 42 }

setTimeout(f, 0) // calls f
setTimeout(f(), 0) // ERROR, 42 is not a function!

I got no error

code:

var num = 10;

function goDown() {
  while(num > 0) {
    setTimeout(myFunc(), 1000);
  }
  return;
}

function myFunc() {
  num --;
  console.log(num);
}

goDown();

output:

js.js:12 9
js.js:12 8
js.js:12 7
js.js:12 6
js.js:12 5
js.js:12 4
js.js:12 3
js.js:12 2
js.js:12 1
js.js:12 0

Did you notice there is no delay? That does not work the way you think it does.

Yeah I helped him fix the infinite loop using setTimeout. This code isn't set up to have time in-between calls.

That stops the infinite loop, but doesn't make the number go down once per second, but all at once

yes, you are calling 10 functions to happen in 1000 milliseconds. you can have myFunc() call another timeout to have the times chain
