Call parent class method (with this context) in child class

I’ve used JS frameworks in which interaction with a child component calls an action on a parent component. I’m trying to do something similar in plain JS, but don’t really know how. I’m trying to bind the parent this, to the action passed down to the child. But can’t make it work.

Should I just be using events instead? And why use events over this sort of approach?

Here’s the basics of what I’m trying to do:

class Parent {
    constructor(){
        for (let id=0; id<100; id++){
            this.children.push(new Child(id, this.updateParent.bind(this)))
        }
    }
    property = "Parent Property";
    children;
    updateParent(childId){
        // Update parent using child Id
        // I want to use this.property or other this.methods
    }
}

class Child {
    constructor(id, updateParent){

        // Create HTML element
        // Register event for element interaction
        // Upon interaction --
            updateParent(id)
    }
}

const parent = new Parent()

Thanks!

class Parent {
    constructor(){
          this.children = [];
        for (let id=0; id<100; id++){
            this.children.push(new Child(id, this.updateParent.bind(this)))
        }
    }
    property = "Parent Property";
    children;
    updateParent(childId){
        // Update parent using child Id
        // I want to use this.property or other this.methods
        console.log("Parent updated from Child ID: "+childId);
    }
}

class Child {
    constructor(id, updateParent){

        // Create HTML element
        // Register event for element interaction
        // Upon interaction --
            updateParent(id)
    }
}

const parent = new Parent()

class Parent {
  constructor() {
    this.children = []
    for (let id = 0; id < 10; id++) {
      this.children.push(new Child(id, this.updateParent.bind(this)))
    }
  }
  childCount = 0
  updateParent(childId) {
    console.log(`Child ${childId} updating Parent. youngest=${this.youngestChild}, count=${this.childCount}`)
    this.youngestChild = childId;
    this.childCount += 1;
  }
}

class Child {
  constructor(id, updateParent) {
    console.log("Child Born:", id)
    this.id = id
    updateParent(id)
  }
}

const parent = new Parent()
console.log(parent.children)
