What are some common methods for manipulating arrays in JavaScript?

Some common methods include push, pop, shift, unshift, splice, and slice. Would you like details on any specific method?

Can you explain how the splice method works?

Sure! The splice method changes the contents of an array by removing or replacing existing elements and/or adding new elements. You can specify the index to start at, the number of elements to remove, and any elements to add.

What about the slice method? How is it different from splice?

The slice method returns a shallow copy of a portion of an array into a new array. It doesn't modify the original array, unlike splice. You specify the start and end indices.

Can you give me an example of using both methods?

Certainly! For splice, you might do array.splice(1, 2, 'newElement') to remove 2 elements starting at index 1 and add 'newElement'. For slice, let newArray = array.slice(1, 3) would create a new array with elements from index 1 to 2.
