Static variables in JavaScript

Question

How can I create static variables in Javascript?

Answer 1

I used the prototype and that way it worked:

class Cat extends Anima {
  constructor() {
    super(Cat.COLLECTION_NAME);
  }
}

Cat.COLLECTION_NAME = "cats";

or using an static getter:

class Cat extends Anima {
  constructor() {
    super(Cat.COLLECTION_NAME);
  }

  static get COLLECTION_NAME() {
    return "cats"
  }
}
