What are the array mutation methods?

Array mutation methods directly modify the original array.

1. push: Adds elements to the end.
2. pop: Removes the last element.
3. shift: Removes the first element.
4. unshift: Adds elements to the beginning.
5. splice: Adds/removes elements at a specific index.

Example:

const arr = [1, 2, 3];
arr.push(4); // [1, 2, 3, 4]
arr.pop();  // [1, 2, 3]
