Arrays in Javascript

In this chapter, you will learn what is an array in Javascript. Array helps to bundle the different data types in a single variable. An Array is a collection of variables with similar data types as well as different data types. Let’s create an array.

Different ways to create an array in Javascript:

const users = ['John', 'Mark', 'Mickel'];
const users2 = new Array('John', 'Mark', 'Mickel');

console.log(users);
console.log(users2);

// output
// (3) ["John", "Mark", "Mickel"]
// (3) ["John", "Mark", "Mickel"]

const users2 = new Array('John', 'Mark', 'Mickel');

console.log(users[1]);
console.log(users2[2]);

// outputMark
