Array Elements

Each individual value in an array is known as an element.

This array has three elements:

const numbers = [1, 2, 3];

We can access the elements in an array by using their index. Array indices start at 0.

We use bracket notation to access array elements since each index is a number:

const numbers = [1, 2, 3]; console.log(numbers[0]); // 1 console.log(numbers[1]); // 2 console.log(numbers[2]); // 3 console.log(numbers[3]); // undefined (this would be the 4th element)
