polyfill for call 1

polyfill for call

Function.prototype.myCall = function (...args) {
  let obj = args[0]
  const params = args.slice(1)

  obj = {
    fn: this

  return obj.fn(...params)

Here is what the above code is Doing:
1. We’re creating a new object and assigning it to the first argument passed to myCall.
2. We’re adding a new property to the object called fn and assigning it to the function that myCall was called on.
3. We’re invoking the function and passing in the remaining arguments.
