Specializing in JavaScript

JavaScript developer specializations

The broader JavaScript career scope includes a variety of specialty areas. JavaScript developers may focus on front-end or back-end development or work as full-stack developers, depending on their exact skill set.

Additionally, they may concentrate their careers on a particular development niche. For example, some professionals choose to harness their knowledge to become web developers. Along with using JavaScript, a web developer will also leverage HTML, CSS, and other related knowledge to create interactive web pages.

However, there are many other career paths related to JavaScript that are also worth considering. JavaScript developers may work on mobile or web applications, server-side systems, client-side functionality, and more. Plus, they often get to dive into other technical areas, including the aforementioned HTML and CSS, object-oriented programming, frameworks, libraries (like jQuery), open-source tools and code, and many others.

Ultimately, specializing in JavaScript can take a person’s career in many directions. Here is an overview of some of the main specialty areas to consider.

Front-end Development

In many cases, front-end development focuses on web development. Professionals in this arena spend time creating the interfaces end-users engage with when accessing sites through web browsers. They create the layouts, select colors, add navigation options, insert interactable links, place buttons, and set up popups. Plus, many work to ensure that websites show correctly when viewed on a variety of devices.

Along with handling UI/UX-related tasks, front-end developers spend time writing code. They may add animations to specific elements. Plus, they’ll create the code needed to extract data from servers to display information through the web-based user interface.

Building reusable code is also a critical part of the equation for a front-end JS developer career. By using JavaScript to create code that is usable in other projects, it streamlines future development dramatically.

Back-end Development

While not all server-side tech jobs rely heavily on JavaScript, many do require professionals to use JavaScript to handle a variety of tasks. Typically, this involves harnessing the power of Node.js to run JavaScript code on a server. Many of these developers also create the code required to support database interactions, ensuring the client-side part of the application can display the correct information.

Often, back-end development includes data storage and cybersecurity-related duties and functions, too. That ensures that incoming information is properly managed and that all connected systems are suitably safeguarded from intrusions or other cyber threats.

An understanding of front-end technology and programming languages is usually needed to execute the duties of a back-end JavaScript developer. Additionally, other skills related to back-end development – such as database languages and architecture, cloud-based solutions like Amazon Web Services (AWS), and API design and support – are necessary to push your career forward.

Full-stack Development

As a full-stack developer, professionals have the knowledge and skills necessary to handle both front-end and back-end development duties. Essentially, they’re jacks of all trades in this arena, operating as a single person who can handle client-side and server-side coding.

For many professionals moving down the JavaScript career path, working as a full-stack developer isn’t where they begin their careers. Instead, they initially specialize in back-end or front-end development. Then, when the opportunities arise, they hone skills related to the other side of the equation. Once they have a robust enough skill set, they can operate as full-stack development specialists.

Many companies prefer full-stack JavaScript developers because it limits the total size of their needed workforce. They can reduce the total number of team members since full-stack developers understand both sides of the JavaScript code equation.

How to Start a JavaScript Developer Career

For anyone who wants to become a JavaScript developer, the first step they should take is to review the roadmap for a JavaScript developer. That provides an overview of how their careers will unfold, making it easier to plan each step of the broader journey.

However, there are a few basics that almost universally serve as solid starting points. The most critical part of the equation is to learn JavaScript. Fortunately, there are several reliable ways to acquire that skill.

First, checking out some of the best books to learn JavaScript is an excellent way to begin. There are many that focus on aspiring professionals with little to no experience, allowing them to serve as functional primers to ensure people build the necessary foundation.

After familiarizing themselves with various core concepts, moving on to web-based or online courses is an excellent choice. With many of these classes, students get to learn practical application. They’ll get to write pieces of code and test their functionality.

While the types of self-direct learning above can work well on their own, most professionals are well-served by earning formal credentials. The most straightforward option is to get a Bachelor’s degree in a related major, such as web development or computer science. However, bootcamps that come with certificates are also worth considering.

Finally, for those looking to start a JavaScript career, don’t forget to learn any needed supplemental technologies and skills. For example, anyone focusing on front-end web development should hone their HTML and CSS capabilities.

For professionals who aren’t sure what exactly to cover, reviewing entry-level job descriptions is an excellent way to find out what’s necessary. Those will outline the exact capabilities employers are after, giving aspiring pros a clear idea of what they need to know.

JavaScript Developer Roles

JS developer career path

Generally, the JavaScript developer career path is reasonably straightforward. Professionals typically begin in entry-level positions, either as trainees or as junior developers. Then, as they acquire experience and hone their skills, they have the necessary capabilities to advance into the next higher position up the ladder.

Here’s a brief overview of the JavaScript developer roles most professionals work their way through during their careers.


For those looking to start a career in JavaScript development, finding a trainee position is worth considering. These positions are particularly worthwhile for aspiring professionals without much formal education, as these jobs are often focused on learning above all else, not unlike an internship

While in a trainee position, professionals receive ample guidance and support as they assist with a variety of projects. Often, any of their deliverables are carefully reviewed, creating opportunities for in-depth feedback that supports growth. Assignments are also commonly on the simpler side, which can make working in the roles less intimidating to those new to JavaScript.

When working in a trainee developer job, professionals should focus on learning and professional development. These positions mainly exist as skill-building opportunities, so embrace the educational side of the equation as much as possible.

Many trainee positions are inherently short-term. When they are, the primary goal is building up the employee’s skills enough to move them into the next position up the ladder.
