Splice() Method in JavaScript 🔥 #javascript #DSA #javascriptinterview

In JavaScript, splice() is an array method that changes the contents of an array by removing, replacing, or adding elements. It modifies the original array and can return an array containing the deleted elements.

Syntax

- start: The index at which to start changing the array. If negative, it indicates the position from the end of the array.
- deleteCount (optional): The number of elements to remove from the array, starting from the start index.
- item1, item2, ... (optional): The elements to add to the array, starting from the start index. If no elements are specified, splice() only removes elements.
