Before You Hire a JavaScript Developer

It’s important to define what type of JavaScript developer you will need for your project. Below are the three main types:

  1. A Front-End JavaScript Developer
    Front-end development is the process of turning information into a visual interface that allows consumers to interact with the product easily. Developers do this by using HTML, CSS, and JavaScript. When it comes to front-end JS programming, it’s important to evaluate the problem and figure out how to keep it user-friendly.
    Front-end developers are well-versed in dealing with user experience and different devices with varying screen sizes. So, these developers must be able to consider various browsers, operating systems, and devices during a project’s development phase.

  2. A Back-End JavaScript Developer
    A back-end developer is in charge of everything that happens behind the scenes to keep an application running. Their programming is often executed on the cloud and does the majority of the hard work to keep a website or software running. Generally, JavaScript programmers are more concerned with data than with visual presentation, unlike front-end development.


    Back-end development often consists of three major components: a server, an application, and a database. Consequently, this kind of expert must be familiar with and have prior experience with subsets of JavaScript such as Node.js. Furthermore, familiarity with several databases, such as SQL or MongoDB, is essential.

  3. A Full-Stack JavaScript Developer
    A full-stack JavaScript developer will work on both the front-end and back-end of a project. As previously said, one of the benefits of JavaScript is that it enables developers to create both types of code. However, a full-stack developer will often have greater expertise in back-end or front-end development, so it may be helpful to consider this if your organization can benefit from that particular functionality.


What Skills to Look for In a JavaScript Developer

JavaScript is one of the most well-known languages and is highly diverse in its capabilities to create functional websites and software. Similarly, JavaScript engineers vary in their specialties and skillsets.

When you begin looking for a JavaScript engineer and define the role you need them for, it’s crucial to think about the skills this position may require to complete projects successfully. Along with soft skills that are required for the job, here are some technical skills you can also look for if you want to hire a JavaScript programmer that is perfect for your organization:

Skills for Font-End JavaScript Developers

A front-end developer develops and builds websites and web apps using web technologies such as HTML and CSS. These technologies normally run on the Open Web Platform or compile in non-web platform contexts such as React Native. Experienced developers at the front-end should also be aware of frameworks such as AngularJS, ReactJS, VueJS, and others based on JavaScript.

Skills for Back-end JavaScript Developers

Node.js. is the primary JavaScript-based back-end platform. In conjunction with other JS frameworks such as Express.js, Koa.js, it is a very beneficial language to know. JavaScript engineers are typically experienced with SQL or MongoDB, and creating, integrating, and managing databases. For the development of an API, knowledge of GraphQL or REST is essential. You should look for at least one of these API development tools when you hire a JavaScript developer.

Interviewing a JavaScript Developer

Now that you’ve narrowed down the type of JavaScript developer you need and you have come across a few potential candidates, it’s time to interview them.

Interviewing potential job candidates provides insights into the communication abilities and other soft skills of an applicant. Moreover, it gives you the chance to verify that you and the applicant are on the same page about the job requirements. It also provides you the opportunity to answer any questions the candidate may have.

However, a technical interview or the knowledge exam alone can not offer you the best insight on whether your applicant really is an elite JavaScript programmer, or simply someone that has dabbled in the language and then put it down as a skill on their resume.

In a technical interview, you should assess the developer’s foundational knowledge of JavaScript, evaluate their understanding of different techniques used to solve specific problems, and test their knowledge of syntax. You can do this by asking application-based questions and asking them to solve JavaScript problems with code snippets.

You can always ask someone to help put together some questions or utilize a trustworthy source to gather some sample questions and answers if you are unfamiliar with JavaScript. With this method, it is easier to tell who is a JavaScript expert and who is just saying they are.

However, it’s important to keep in mind that completing all technical questions properly alone does not guarantee that someone is the best JavaScript programmer. Instead, use the technical interview as a roadmap to find the best developer for your team.


Final Words on How to Hire a JavaScript Developer

Hiring a JavaScript developer can be challenging. The programming language is versatile, and there are many different ways to use it for various projects. Not all developers are skilled in every aspect of the language. You want to make sure you hire an expert in the field to provide you with the best project outcome. Fortunately, we are here to help.
