JavaScript Tutorial

Initially, when JavaScript was created, it was called “LiveScript”. Then, as Java was extremely popular in that period, then it was decided to call it JavaScript to position it relative to Java. But, over the years, JavaScript has transformed into a completely independent language, with its specification, known as ECMAscript, having no relation to Java.

As an object-oriented language (OOP), JavaScript depends on objects, or data structures that hold data and the applicable functions. OOPs are designed to allow coders to structure and modify programs quickly. This Javascript Training Certification includes comprehensive 83 courses with 235+ hours of video tutorials and Lifetime access and several mock tests for practice. You will also get verifiable certificates (unique certification number and your unique URL) when you complete each of the courses.


Developers who know JavaScript can also use libraries like Reveal.js, Swiper.js, Greensock.js and Anime.js, to enhance their images and animations. JavaScript’s creators developed the language to address the new programming challenges posed by the internet. Before JavaScript, server-side languages were required to validate any data entered into a website, JavaScript Lessons which made interactive features clunky at best. Making matters worse, most users at the time relied on dial-up connections, which slowed the communication between servers and web pages to a glacial pace. In addition, many of the leading frameworks that power cutting-edge web development today, such as Node.js, jQuery and React, run on JavaScript.

We concentrate on the language itself here, with the minimum of environment-specific notes. We want to make this open-source project available for people all around the world. Always make sure you understand all the “Try-it-Yourself”


Today, JavaScript is a fully fledged language that can facilitate complex interactions and build dynamic, engaging website features. Modern browsers like Google Chrome, Mozilla Firefox and Microsoft Edge are built to handle JavaScript quickly and accurately. In this SoloLearn course, you will learn about conditions, loops, functions, objects, arrays, the DOM, and events.

In this module we will explore what APIs are, and how to use some of the most common APIs you’ll come across often in your development work. JavaScript is an actively evolving language and has changed greatly over the years. In particular, the 6th edition of the language (sometimes known as ECMAScript 2015 or ES6), introduced in 2015, added many new features. At the same time, to maintain backwards compatibility with older websites, old features of the language have been retained, even when they are no longer considered good practice.
