Make a javascript method execute every n milliseconds

Question

I have read this post about executing a function every n seconds, but I am working with classes and want to execute the method every n seconds.

I have 2 objects, and each one will have a method that will execute every n seconds.

class MyClass {
  constructor() {
    //stuff
  }
  myMethod() {
    //other stuff to execute every n seconds
  }
}

var obj1 = new MyClass()
, obj2 = new MyClass();

How would I go about doing this?

EDIT: Sorry for the confusion, but i wanted to be able to use the this keyword in the interval

How did the answers from the question you linked not help you? Have you tried using `setTimeout` or `setInterval`? Please post the code of that attempt. — Bergi, Jan 20 '20 at 00:27

You can simply use setInterval to call a function every n milliseconds:

class MyClass {
  doSomething() {
    console.log('doSomething() called..')
  }
}

var o = new MyClass();

setInterval(o.doSomething, 1000);

@Ankizle: https://stackoverflow.com/q/20279484/218196 . Use `setInterval(() => o.doSomething(), 1000)` instead. – Felix Kling Jan 20 '20 at 01:16

If i use `self` i cannot set new values – Ank i zle Jan 20 '20 at 01:17

@Ankizle: There is more than one solution. `self` isn't applicable in your case. Please read the whole answer. Make sure you understand how `this` behaves. – Felix Kling Jan 20 '20 at 01:19
