How to access your own property in a module method if someone else's context is attached?

Question

JavaScript

There is a module like:

/*  AB.js  */
export default {
  a: 'AAA',
  b: function() {
    this.a = '3 A';
  }
}

But the method b()is called with another context attached:

import AB from './AB'

setTimeout( AB.b.bind(null), 0);

b()How can I make my own property available in a method a?

Answer 1

const self = {
  a: 'AAA',
  b: function() {
    self.a = '3 A';
  }
}

export default self;

Answer 2

Лучше вообще просто стрелочную функцию использовать в AB.js.
