What is the splice method in JavaScript arrays?

Can you explain the splice method in JavaScript arrays?

Sure! The splice method is used to add or remove items from an array. It modifies the original array.

How do I use it to remove elements?

You can use splice(index, count) where 'index' is the starting position and 'count' is the number of elements to remove.

Can you give me an example?

Of course! If you have an array like let arr = [1, 2, 3, 4]; and you call arr.splice(1, 2);, it will remove 2 and 3, leaving you with [1, 4].

What if I want to add elements instead?

You can use splice(index, 0, element1, element2...) to add elements without removing any. For example, arr.splice(1, 0, 5); adds 5 at index 1.
