Example

import bind from 'bind-x';

this.x = 9; // this refers to global "window" object here in the browser
const module = {
  x: 81,
  getX: function() {
    return this.x;
  },
};

console.log(module.getX()); // 81

const retrieveX = module.getX;
console.log(retrieveX());
// returns 9 - The function gets invoked at the global scope

// New programmers might confuse the
// global var x with module's property x
const boundGetX = bind(retrieveX, module);
console.log(boundGetX()); // 81
