 Arrays are list-like objects that contain multiple values stored in a list.

 Eg. var fruits =["apple","orange","banana"]

fruits[0]//to select apple 

friuts[1]//to select orange

fruits[2]//to selecr banana,etc

const fruits = ["Apple", "Banana"];

const newLength = fruits.push("Orange");

console.log(fruits);

// ["Apple", "Banana", "Orange"]

console.log(newLength);

// 3

const fruits = ["Apple", "Banana"];

​

fruits.includes("Banana"); // true

fruits.includes("Cherry"); // false

​

// If indexOf() doesn't return -1, the array contains the given item.

fruits.indexOf("Banana") !== -1; // true

fruits.indexOf("Cherry") !== -1; // false
