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.

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.

JavaScript is a complicated but not too difficult to learn programming language that is sometimes referred to as the "language of the internet." It is a commonplace in web2 as well as web3 technologies.
JavaScript allows you to build on a blockchain, and since it's a language that many web browsers are already acquainted with, it's used with both WebVR and WebAR apps. Because it can be put to use in such a wide variety of situations, JavaScript is the language that experts and companies advise novice programmers to study if they are looking for a risk-free option to learn.

When it comes to the front end of an application, there are so many Javascript frameworks and libraries available that it is difficult for developers to select the ideal one. You can select either Vue.js, React.js, or Angular.js based on two considerations: learning curve and employment outlook. These client-side frameworks and libraries are in great demand on the job market, and the majority of businesses use them to develop apps.
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.

Where to Learn JavaScript Development Skills
The Internet is primarily a reservoir of information. Whether you are interested in self-directed learning or lack time to enrol in a formal program, flexible online courses may be the solution to your educational needs.
These free and paid online courses will teach you JavaScript quickly, but remember that "free" does not necessarily mean "better." Typically, free applications give less guidance and less support than their premium counterparts. Be careful to do research before enrolling in your first class.
In recent years, boot camps have risen to prominence as a technique to acquire valuable skills rapidly and without investing the time or money required by regular four-year schools. The typical duration of a boot camp is from a few weeks and a few months, depending on whether it is part-time or full-time.
