Introduction to JavaScript Arrays

Introduction to JavaScript Arrays

Arrays are used to store a collection of values in a single variable. In this tutorial, we will cover the basics of JavaScript arrays.

Creating an Array

To create an array in JavaScript, you can use the [] syntax or the Array constructor. Here is an example of how to create an array:

let fruits = ['apple', 'banana', 'orange'];

Accessing Array Elements

To access an element in an array, you can use the index of the element. Here is an example of how to access an array element:

let fruits = ['apple', 'banana', 'orange'];
console.log(fruits[0]);

Array Methods

JavaScript arrays have several built-in methods, such as push, pop, shift, and unshift. Here is an example of how to use some of these methods:

let fruits = ['apple', 'banana', 'orange'];
fruits.push('grape');
console.log(fruits);
fruits.pop();
console.log(fruits);
