Implement Array.prototype.map

Implement a custom Array.prototype.myMap method that works similarly to Array.prototype.map.

myMap creates a new array by applying a callback function to every element of the original array.

Requirements

• Add a method named myMap to Array.prototype.
• myMap(callback) must:
  • Return a new array (do not mutate the original array).
  • Call callback for each index from 0 to array.length - 1.
  • Call callback with arguments: (currentValue, index, array).
  • Produce a result array where each entry is the return value of callback at the same index.
• If callback is not a function, throw a TypeError.

Constraints

• Do not use the built-in Array.prototype.map.

Example

const numbers = [1, 2, 3, 4, 5];

const squaredNums = numbers.myMap((number) => {
  return number * number;
});

console.log(squaredNums); // Output: [1, 4, 9, 16, 25]
