JavaScript, also known as JS, is the scripting language used to make your website or web app interactive. It is one of the essential languages in web development along with HTML and CSS. You can add life to the annoying static webpage with JavaScript, and many who wish to enter the web development field opt for professional JavaScript certification and courses.

People get confused between JavaScript and Java. But both have different purposes and differ in terms of design and syntax. There is no relation between these two languages except having a similar name. If you are looking for JavaScript certification courses, this is the right place to find it.

Why Opt For JavaScript Certification Courses

Many reasons make JavaScript famous among students and professionals in the IT or precisely web development field. One of the most important goals is to create interactive websites. In simpler terms, JavaScript can add animation, respond to the user’s interaction, and make the website dynamic.

You can get started with JavaScript without any development setup, as all the browsers have inbuilt JavaScript engines to execute the JavaScript code. This language is used in smart TVs, IoT, and mobile app development as well. So, its reach is beyond web development nowadays. Initially, JavaScript was developed and used for client-side coding, but now with Node.js, you can also use it for server-side programming.

The career potential with JavaScript is skyrocketing because of its versatility and ease of learning. You can learn advanced languages like JSON, Node.js, and AngularJS once you know JavaScript. The other technology courses, when taken with JavaScript, can add to your resume and increase your knowledge.
