Introduction

JavaScript provides built-in tools called methods to manage array data. Developers use these methods to add new items to the end of a list, remove the first item, or sort everything alphabetically.

Example

1/* this uses array methods */
2const fruits = ["Banana", "Orange"];
3fruits.push("Apple"); // Adds Apple to the end
4fruits.pop(); // Removes Apple

Key Points

The `push()` method adds items to the end.
The `pop()` method removes the last item.
The `length` property counts the total items.
The `join()` method converts the array into a string.
