Let me start this top 20 JavaScript courses blog by giving a small description of what it is: this blog is a treasure trove of knowledge about JavaScript for those who have made a career in this programming language and want to grow in it. This blog lists not one, not two, but as many as 20 top JavaScript courses that you can choose from, which will help you soar in your career in web software development. So, fasten your belts and get prepared to explore JavaScript in all its depth.

But first, let us understand a few things about JavaScript briefly. If you have chosen a career in web development, great for you. Because, web development is something of a career that will feed countless mouths as long as the www exists, and this means that we are talking of a period up to which businesses and other organizations use websites. So, for those who want to choose web development, the road ahead is a long, smooth one.

The surest way of traveling this road and reaching your destination is by choosing JavaScript. The JavaScript programming language is as vital to web development as racquets to tennis. What makes JavaScript so indispensable to web development? The answer is very simple: it is because of JavaScript that webpages get the interactivity needed to behave the way they do. So, you get an idea of how crucial it is for any organization to have JavaScript developers that can make websites interesting, engaging, and productive.

What is JavaScript?

Let us get basic things sorted out first. Let us start with an understanding of JavaScript. The JavaScript programming language has a few core characteristics. It is:

• Lightweight
• Interpreted
• Cross-platform
• Open

So, what it is used for? The JavaScript programming language is primarily used for creating network-associated applications. The main feature of its existence is that it is complementary to and integrated with java. Since it is also aligned with Html, it is very easy to use it for websites.

Reasons for which you should study JavaScript

Well, I just mentioned the criticality of JavaScript to software in web development. There are a number of reasons for which anyone who is interested in web development should take up courses in JavaScript:

• Three-fourths of IT organizations around the world have a need for JavaScript developers; yet, only around half of them get the right fit. This means that there is a huge global market waiting to pounce on the rightly qualified JavaScript professional.
• In 2018-19, it was the most sought after skill in the IT industry the world over
• Learning JavaScript puts you directly on the road to learning JavaScript frameworks such as jQuery, NodeJS, etc., which are frontend and backend applications
• Its many libraries and frameworks, such as Angular, React, jQuery, Vue.js, Meteor, Mithril, Node.js, Aurelia, etc. help you develop and market your software faster than one can think of.

Now, the top 20 JavaScript courses So, I now come to the heart of the matter as far as this blog is concerned.
