1. What Should You Know?

The formal introduction of a JavaScript developer starts with a definition explaining it to be a software programmer who codes for front-end website and server-side for an application. The absence of JS code would only lead to displaying static content. A JS developer extends the skills to a website’s front end to provide web pages a dynamic functionality.

2. Technical Knowledge

The skillset of a JS developer is not limited to testing and debugging the code, but it also extends to problem-solving skills and creativity. Below are core JavaScript programming language skills.

2.1. Programming Languages

It is highly significant for a JS developer to understand frameworks such as Node.js, libraries like jQuery, browser APIs, and npm packages.

Specifically, a JS developer would have hands-on knowledge of return statements, error handling, array manipulation, and string manipulation. Additionally, they must know the new trends added to the core language introduced in JavaScript ES6 and drive their working with a class and all about promises, modules, and generators.

2.2. Web Design Basics

A web page consists of JavaScript, HTML, and CSS; hence a JavaScript developer must be well-versed with how to work on HTML, CSS code, and DOM-Document Object Model. Here, having basic design knowledge would be beneficial, that helps to streamline the design from the perspective of technology as well.

2.3. JavaScript Frameworks

Any commercial project gets built using a framework that encourages faster development with pre-written and pre-tested code for common functions. Some of the most popular front-end JavaScript frameworks are Angular, React, and Vue.js. And the list of popular back-end JavaScript frameworks is Node.js and Next.js.

2.4. Performance Optimization

Well, this is another essential segment that must be considered while hiring a JavaScript developer. Any code can experience a slow pace due to multiple reasons; here, a javascript developer must know how to optimize the performance of their code. They must know, every if and but about the language to troubleshoot the error and let the code run effortlessly.

3. Roles of Developers

There are majorly three segments where JavaScript developers are being utilized as:

• Front-End
• Back-End
• Full-Stack

3.1. Frontend Developers

This is the client-side interface, where the developer works on transforming information into a graphical interface, making the product user-friendly. This task is carried out with the technology set of HTML, CSS, and JavaScript. Also, they work with programming languages such as ReactJS, Angular JS, VueJS, MeteorJS, and apply JavaScript libraries like JQuery and LESS. And they carry out UI tests and remove bugs and build RESTful APIs.

3.2. Backend Developers

In this process, there are three main segments: a server, an application, and a database. So, a back-end developer must have the competency to handle, code, test, and operate Node.js., and managing the demands of a database like SQL or MongoDB is also important.

These developers implement user-facing parts with server logic by applying programming languages like Python, Perl, Java, Ruby, PHP, .Net. And apply 2EE, Nginx, Apache, IIS – solutions for static content management, along with Git, Subversion (SVN), and Concurrent Versions System (CVS) – version operation software systems.

3.3. Full Stack Developers

These JS developers are multi-skilled and can be picked for developing prototypes. However, while selecting, you need to be sure of their skills. With a Full Stack JavaScript Developer, you attain a final product that is a perfect solution for your business needs.

They further have an in-depth understanding of the latest front-end technologies and a specialization in working simultaneously with the back-end and front-end to fulfill your project’s requirements.

In the end, while hiring a JavaScript developer for your project, you must ensure that the hired resource has the required expertise to tackle the technical challenges and can work efficiently with JavaScript development, depending upon the project’s complexity, features, security, budget constraints, and timeline among many other factors.
