By | October 25, 2021

JavaScript’s adoption has surged in recent years, and it has now established itself as the de facto language for web development. For the seventh year in a row, JavaScript has ranked among the most widely used programming languages. JavaScript is currently used by 94.5 percent of all websites on the internet and is now supported by all browsers, making it an essential web technology alongside HTML and CSS.

Based on a lot of metrics, we’ve compiled a list of the best online JavaScript courses to help you learn JavaScript from top-rated instructors all around the globe. You can begin coding in JavaScript right away and eventually master it by taking one of the JavaScript online classes listed in this blog post.


What is JavaScript?

JavaScript is a dynamic programming language that was launched in the year 1995. It is a lightweight component of websites that enables client-side scripts to interact with users and create dynamic websites. It’s an object-oriented programming language that can be interpreted.

Javascript allows you to create interactive websites, web apps, mobile applications, desktop apps, and visuals. Also, it can be used for game development and the Internet of Things (IoT). To be a successful developer, whether working on front-end or back-end development projects, Javascript can come in quite handy.

Angular, React, and jQuery are among the widely popular and powerful web development frameworks based on this programming language. So, if you want to boost your employability, understanding JavaScript is a must.

Below are some of the key benefits of using JavaScript:

  • Less server interaction: Before transmitting the webpage to the server, you can check input validation. This reduces server traffic, resulting in lower stress on the server.
  • Immediate responses: Visitors don’t have to wait long for websites to load. This potentially reduces the bounce rates and exit rates.
  • Rich user interface: To provide a rich interface to your site users, you can utilize JavaScript to incorporate features like drag-and-drop components and sliders.
