JavaScript is one of the most popular and widely used programming languages with the most rapid adoption rate. The continued rise in popularity of JavaScript may be attributed largely to the recent expansion of top UI frameworks, in addition to web and cross-device libraries. There is a growing need for JavaScript developers in every sector, so it should come as no surprise that this programming language is becoming more popular among those seeking to improve their skills or switch industries. Stay with us to know the career opportunities in JavaScript development. What Are the Duties of a JavaScript Developer JavaScript developers work in the area of building interactive web pages, as was previously indicated. Their major responsibility is to conceptualise and build internet apps for their customers. In order to construct these applications, they use markup languages such as HTML, CSS, and JSX, as well as other frameworks. In addition to that, they examine the correctness of the code and deal with issues about the compatibility of different browsers. A programmer has the ability to produce pre-written code for projects when using an object-oriented language like JavaScript. This is one of the advantages of utilising such a language.  Read: Virtual Reality Developer Career Path: How to Become a VR Developer JavaScript programmers have the ability to construct libraries consisting of pre-written code sections known as JavaScript functions or modules. Because of this, the time spent developing code and going through the whole process again for each new project will be reduced. Developers of software produced using JavaScript are accountable for ensuring the program's continued high quality and proper operation. Performing tasks such as putting newly developed JavaScript features through their paces and addressing any issues that crop up, as a result, are required here.  Furthermore, they keep a close eye on performance and carefully examine the end findings of any testing. After that, the results were included in the reports that were sent out to the various stakeholders involved in the project. Read: Career Opportunities in Meta: How to Prepare for Jobs at Metaverse?

JavaScript is not restricted to browsers alone; it can also be executed outside of the browser, and NodeJS is the technology that makes this possible. NodeJs is a robust runtime environment that allows JavaScript to be used as a back-end programming language. In recent years, developers have favoured using NodeJS coupled with ExpressJS, Node's framework, which is extensively used to create back-end APIs. Therefore, we strongly advise you to study both of them.
