Calling Function from another JS file(not a game state) Phaser js

Question

import Timer from '../components/Timer.js';

export default class MainGame extends Phaser.State {
    preload() {
        console.log("create");
    }
    create() {
        this.timerJS = new Timer(this.game);
    }
    update() {

    }
}

The above code is my MainGame state code. In create I have created Timer.js object. Now, how to call foo() which is written in Timer.js file. Timer.js is not a state, but just a simple js file.

Answer 1

If instantiating a new variable reference of a class, you can simply call methods on the class from the variable you create.

So in this case, to call method foo() , simply:

this.timerJS.foo()
