Custom implementation of the bind function

You need to write a function myBind(fn, context) that returns a new function. When this new function is called, the original function fn should execute in the provided context and accept any arguments passed to it.

const obj = {
  a: 1,
  show(num) {
    if (num !== undefined) {
      console.log(this.a + num);
      return;
    }
    console.log(this.a);
  },
};

const fn = obj.show.bind(obj);
fn();

myBind(fn, obj)();

The example demonstrates how the standard bind attaches the show method to the obj object. Your task is to implement a similar mechanism without using the built-in Function.prototype.bind. The function should work correctly both with and without arguments.
