Does setImmediate clears existing objects ?

[arka1002]

Minimal repro, see line 5 of index.js - https://stackblitz.com/edit/stackblitz-starters-vvyzjf?file=index.js
Please run - node index.js in the terminal to reproduce

class Zoom {
  kid = 5;
  hush() {
    console.log(this.kid);
  }
}

const foo = new Zoom();
foo.kid = 4;
setImmediate(foo.hush); // But, why this is undefined ?
foo.hush(); // this prints 4, which I understand

Can anyone kindly explain why this is happening ? I couldn't find any info regarding existing objects in https://nodejs.org/en/learn/asynchronous-work/understanding-setimmediate.

It has nothing to do with setImmediate, it has to do with the function not being bound.
