Javascript splice method how to delete an item from an array

the javascript `splice` method is a versatile function used to modify arrays by adding or removing elements. to delete an item from an array, you can specify the starting index of the element you want to remove and the number of elements to delete. when you invoke `splice`, it alters the original array directly and returns an array containing the removed items. this method can be particularly useful for dynamic data manipulation, as it allows for both the removal and insertion of items within a single operation. additionally, `splice` can handle multiple deletions at once if needed, making it a powerful tool for managing arrays. it's important to note that since `splice` modifies the original array, it does not create a new array, which distinguishes it from other methods like `filter` or `slice` that return new arrays. overall, `splice` is essential for effective array management in javascript.
