deleteJ

deleteJ is a JavaScript function designed to remove an element from an array based on its index. It takes two arguments: the array from which to remove the element and the index of the element to be removed. The function returns a new array with the specified element omitted, leaving the original array unchanged. This immutability is a key feature, making deleteJ suitable for use in applications where preserving the original data structure is important, such as in functional programming paradigms or state management libraries.

The implementation of deleteJ typically involves using array slicing. It first creates a new array containing all elements from the beginning of the original array up to, but not including, the specified index. Then, it creates another new array containing all elements from the index immediately following the specified index to the end of the original array. Finally, it concatenates these two new arrays to form the resulting array without the element at the given index. This approach ensures that the original array remains unmodified.

deleteJ is a straightforward utility function that simplifies the process of removing array elements by index while maintaining data integrity. Its primary purpose is to provide a clean and predictable way to manipulate arrays in JavaScript, particularly in scenarios where immutability is a design consideration.
