Implementing a Drop Function in JavaScript

The drop function is a common utility in functional programming that removes a specified number of elements from the beginning of an array. This is useful for processing data streams, skipping initial headers in files, or generally manipulating arrays in a concise and declarative way. Your task is to implement this function in JavaScript.

Problem Description

You need to implement a function called drop(arr, n) that takes an array arr and a non-negative integer n as input. The function should return a new array containing all elements of arr except for the first n elements. The original array arr should not be modified.

Key Requirements:

• The function must return a new array.
• If n is greater than or equal to the length of arr, the function should return an empty array.
• If n is 0, the function should return a copy of the original array.
• The function should handle arrays containing any data types.

Expected Behavior:

The function should efficiently remove the specified number of elements from the beginning of the array and return the remaining elements in a new array.

Edge Cases to Consider:

• n is negative (should be treated as 0).
• arr is an empty array.
• n is equal to the length of arr.
• n is greater than the length of arr.
• arr contains mixed data types.

Examples

Example 1:

Input: [1, 2, 3, 4, 5], 2
Output: [3, 4, 5]
Explanation: The first 2 elements (1 and 2) are dropped, leaving [3, 4, 5].

Example 2:

Input: ['a', 'b', 'c', 'd'], 0
Output: ['a', 'b', 'c', 'd']
Explanation:  `n` is 0, so the original array is returned as a copy.

Example 3:

Input: [true, false, true, false], 4
Output: []
Explanation: `n` is equal to the length of the array, so an empty array is returned.

Example 4:

Input: [10, "hello", true, null], 1
Output: ["hello", true, null]
Explanation: The first element (10) is dropped.

Constraints

• arr will be an array.
• n will be a non-negative integer.
• The time complexity of the solution should be O(N), where N is the length of the array after dropping elements.
• The space complexity of the solution should be O(N), where N is the length of the array after dropping elements (due to creating a new array).

Notes

Consider using array slicing or other efficient array manipulation techniques to implement the drop function. Think about how to handle the edge cases gracefully and ensure the function behaves as expected in all scenarios. Avoid modifying the original array.
