Arrays are variables which can hold more than one value

const fruit = ["banana", "apple", "grapes"]
const a, = [7, "Arpan", true]  -  Can be different types

Accessing values

let numbers = [1,2,7,9]

numbers[0] - 1
numbers[1] - 2

Finding the length

let numbers = [1,2,7,9]

numbers.length - 4

Changing the value

let numbers = [1,2,7,9]

numbers[2] = 8 - numbers now becomes [1,2,8,9] arrays are mutable, arrays can be changed

In javascript, arrays are objects. The typeof operator on array return an object

const n = [1,7,9]

typeof n - returns "object"

Array can hold many values under a single value
