JavaScript Tutorials

So on demand of Netscape, Brenden Eich, in 1995 invented a prototype based language for their Navigator Browser. Initially it was called “LiveScript”, but later on renamed as “Javascript”. In Stack Overflow survey 2015, JavaScript was the second most popular programming language in the world. Whenever we write JavaScript, the browser will execute that code for us.

This will help you work with classes and objects in JavaScript. A web application is meant to be interactive and should be smart enough to validate the information stored by the end-user. And here’s where JavaScript Form Validation comes into play! Just like the name goes – form validation – checks and validates whether or not the provided information or data is accurate or not. Learn all about it in this lesson of the JavaScript tutorial.

Section 1. Getting started

JavaScript is a light-weight object-oriented programming language which is used by several websites for scripting the webpages. It is an interpreted, full-fledged programming language that enables dynamic interactivity on websites when applied to an HTML document. It was introduced in the year 1995 for adding programs to the webpages in the Netscape Navigator browser. Since then, it has been adopted by all other graphical web browsers. With JavaScript, users can build modern web applications to interact directly without reloading the page every time. The traditional website uses js to provide several forms of interactivity and simplicity. JavaScript has various fundamental elements, such as variables, functions, control flow, and data types, among others.

Conditional Flow in JavaScript

Later in this tutorial, we will implement a “time travel” feature that allows us to review the tic-tac-toe game’s history and “jump back” to previous moves. This functionality isn’t specific to games — an ability to undo and redo certain actions is a common requirement in applications. Avoiding direct data mutation lets us keep previous versions of the game’s history intact, and reuse them later. Take an introductory level JavaScript class at edX and learn about syntax, conditionals, and programming for web applications.
