'this' is undefined in JavaScript class methods

Question

I\'m new to JavaScript. New as far as all I\'ve really done with it is tweaked existing code and wrote small bits of jQuery.

Now I\'m attempting to write a \"class\"

Answer 1

This question has been answered, but maybe this might someone else coming here.

I also had an issue where this is undefined, when I was foolishly trying to destructure the methods of a class when initialising it:

import MyClass from "./myClass"

// 'this' is not defined here:
const { aMethod } = new MyClass()
aMethod() // error: 'this' is not defined

// So instead, init as you would normally:
const myClass = new MyClass()
myClass.aMethod() // OK
