array example js

Example 1: what are the two ways to create an array in javascript examples?

let scores = Array(10);

Example 2: js arrays

// Making an array:
const colors = ["red", "orange", "yellow"];

// Arrays are indexed like strings:
colors[0]; // "red"

// They have a length:
colors.length; //3

// Important array methods:
//push(value) - adds value to the END of an array
//pop() - removes and returns last value in array

//unshift(val) - adds value to START of an array
//shift() - removes and returns first element in an array

Example 3: access index of array javascript

let first = fruits[0]
// Apple

let last = fruits[fruits.length - 1]
// Banana
