# Methods

Let's create an array:

var fruits = ['peach', 'banana', 'lemon', 'strawberry'];

You see that we use square brackets [] to create an array.

# Length

We can get how many items are in an array with the length attribute:

console.log(fruits.length); // 4

# Getting items

Arrays are ordered which means that the each item is stored in a numbered position/slot.

You can get any value from an array through an index:

var firstItem = fruits[0];
console.log(firstItem); // peach

# Adding items

We can add items by calling the push() function with new value(s):

fruits.push('apple');
fruits.push('blackberry', 'mango');

# Removing items

We can delete/remove the last item from an array by calling the pop() function:

fruits.pop();

# Updating items

You can change the value of an item by using the index:

fruits[2] = 'pineapple';

# Any type

You can add items of different types in an array:

var stuff = [32, 'bike', false, [12, 32]];
