How to Hire JavaScript Developer

For many years, JavaScript has been at the forefronts of most of the interactive websites and web apps you see today. JavaScript goes beyond the front end, creating full-featured websites and applications with modern JavaScript frameworks and tools. 

Here at Full Scale, we also have our shares of ups and downs when it comes to hiring a high-skilled JavaScript developer. An experienced developer can be challenging as demand is high and competition is steep. So, we wrote this blog post to give you a comprehensive guide to finding that exceptional JavaScript developer. 

It is one of the most widely used programming languages, making it a popular technical skill among newbie and experienced developers. So, if you’re reading this because you’re planning to hire a JavaScript developer to work on a development project, then you’ve come to the right place. 

What does a Javascript Developer do?

There are different types of JavaScript developers depending on the roles they need to perform. These are the front-end developer, back-end developer, and full-stack developer. 

The JavaScript language was originally intended for developing the front end of websites and applications. However, it has extended to the back end. Using the JS Framework, they also power interactive games, smartwatch apps, and hybrid mobile apps. 

Type of JavaScript Developers

Front-end Javascript Developer

Experts on front-end JavaScript development are primarily responsible for converting data into a graphical user interface so users can interact with electronic devices easily. They make websites visually-appealing and simple to use. 

It’s a must for front-end developers to fully understand CSS and HTML (besides JavaScript), design and user experience. In other words, they are responsible for making things on the outside look great and transform mock-ups into active graphic interfaces. 

Back-end Javascript Developer

If you need someone to take care of your apps and website’s behind-the-scenes, then a back-end JavaScript developer is for you. They help access and manage server-side data and enable websites to be responsive. Back-end development often involves a server, database, and application. A back-end JavaScript developer should have extensive knowledge in JavaScript languages such as Express.js and Node.js, and databases such as MongoDB and SQL.

Full-stack Javascript Developer

A full-stack developer is considered a generalist as they can do both front-end and back-end coding. However, this doesn’t necessarily mean that they are an expert in any of the stacks.  So, their skills and experience are more versatile as they can work on both types of coding. 

If you need an expert to manage all parts of your website, then hiring a full-stack developer will make sense. They are great at prototyping and creating apps from scratch but may not be the right choice to do detailed design requirements and creating a database architecture.
