Implement the call function

# Introduction

In this challenge, we will tackle a real interview question - implementing the `call` function. The purpose of this lab is to encapsulate a `myCall` function that mimics the functionality of the `call` function in JavaScript. This function takes in a function to be executed and an explicitly changed `this` pointer as parameters, along with any additional parameters for the function. The goal is to successfully execute the passed function with the provided `this` pointer and parameters.
