# Array Basics & Indexing — JavaScript

> Creating arrays and accessing elements by index.

## Creating & indexing

Arrays are zero-indexed, and `.length` always reflects the current size.

```js
const fruits = ["apple", "banana", "cherry"];
console.log(fruits[0]);        // apple
console.log(fruits.length);    // 3
console.log(fruits[fruits.length - 1]); // cherry
```

## Arrays are objects

Arrays are a special kind of object with numeric keys and a `length` property that updates automatically.

## Out-of-range access

Accessing an index beyond the array's length returns `undefined`, not an error.
