Javascript 30 array Methods

first I will discuss about map method.

The map() method in JavaScript is used to iterate through each element of an array and apply a provided function to each element. It then creates a new array containing the results of applying the function to each element. This is a powerful way to transform elements without modifying the original array.

Usage: array.map(callback(element, index, array))
Parameters:
callback: A function that is called for each element in the array.
element: The current element being processed.
index: The index of the current element.
array: The array being iterated.
Returns: A new array with the transformed values.
