Polyfill for bind method

PolyfillBind.js

const person = {
  name: "Juan",
  lastName: "Ortiz",
}

const printName = function() { // Important this can't be arrow function
  console.log(`${this.name} ${this.lastName}`);
}

const printPerson = printName.bind(person);
printPerson();

// My custom implementation
Function.prototype.myBind = function(...args) {
  const obj = this;
  const params = args.slice(1); // this is for simplicity
  return function() {
    obj.apply(args[0], params);
  }
}

const printPerson2 = printName.myBind(person);
printPerson2();
