override a getter on a subclass in javascript

To override a getter in a subclass in JavaScript, you can define a new getter with the same name on the subclass. This will shadow the getter on the parent class and will be used instead when accessing the property on instances of the subclass.

Here's a simple example:

index.tsx
class Parent {
  get prop() {
    return "parent";
  }
}

class Child extends Parent {
  get prop() {
    return "child";
  }
}

const parent = new Parent();
console.log(parent.prop); // "parent"

const child = new Child();
console.log(child.prop); // "child"
260 chars
18 lines

In this example, the Parent class defines a getter for the prop property that returns the string "parent". The Child class extends Parent and defines its own getter for prop that returns the string "child". When we create instances of Parent and Child and access the prop property, we get the expected values. The getter on the subclass overrides the one on the parent class.

Note that getters are accessed using the same syntax as object properties, so you don't need to call them explicitly like methods. Also, the super keyword can be used inside the getter of the subclass to access the parent class's implementation of the getter, if needed.
