35. Function.prototype.call

Implement your own version of Function.prototype.call method. The call method calls a function with a given this value and arguments provided individually.

Requirements

1. Basic Functionality

• Accept a thisArg parameter to be used as the this value
• Accept individual arguments (not an array)
• Call the function with the specified this context
• Return the result of the function call

2. Edge Cases

• Handle null or undefined as thisArg (should default to global object)
• Support functions with any number of arguments (including zero)
• Work with both function declarations and arrow functions (where applicable)

Example Usage

function greet(greeting, punctuation) {
  return `${greeting}, ${this.name}${punctuation}`;
}

const person = { name: 'Alice' };

// Using built-in call
greet.call(person, 'Hello', '!'); // "Hello, Alice!"

// Using your implementation
greet.myCall(person, 'Hello', '!'); // "Hello, Alice!"
