JavaScript Developers Hiring Guide

When you're looking for the best JavaScript developers, what should you look for?

JavaScript is a scripting language that allows developers to add complex features to web pages in a simple and straightforward way. Whenever you see a site that does more than just lay flat on the page, chances are likely JavaScript is behind whatever is happening. Some of those things include:

  • Timely content updates
  • Interactive maps
  • Animated graphics
  • Scrolling video or images
  • Audio
  • Accordion menus

The list of what JavaScript can add to a website goes on and on. This is the main draw of JavaScript—to evolve websites into boring, static pages and into exciting, interactive environments. Because of that, your business should consider JavaScript a must-have for website development. 

JavaScript is often considered one of the three most important building blocks for websites, which are:

  • HTML
  • CSS
  • JavaScript

With those 3 tools, you can build rich, dynamic websites that will keep customers coming back.

JavaScript is one of the most popular programming languages in the world and has been around for over 25 years. First released on December 4, 1995, JavaScript was created as a just-in-time compiled, multi-paradigm language that supports event-driven, functional, and imperative programming styles. The JavaScript engines were originally limited to web browsers, but have since migrated to servers and applications. 

Although JavaScript shares some similarities to Java (such as syntax and standard libraries), the 2 languages are quite different. 

Back in the early days of the internet, web pages were all static, so they lacked any type of dynamic behavior once a page was loaded into the browser. It was then that the management of Netscape (one of the first graphical web browsers) decided to devise a new language that would extend the capabilities of theirs. In 1995, Netscape added a scripting language to the browser. This implementation was originally called LiveScript but was soon changed to JavaScript.

The language has evolved a lot since then. With modern JavaScript, the possibilities are almost endless. You can add features like this to your website:

  • Loading of new content without forcing a browser reload
  • Animations like fades, resizes, and moving
  • In-browser games
  • Media stream playback control
  • Popups
  • In-browser web form validation
  • Logging user data

Of course, JavaScript isn't limited to web pages. Your company can leverage this language for:

  • Mobile app development
  • Serverless websites
  • Progressive web applications
  • Embedded systems (like Drones)

And although JavaScript might be harder to learn than a language like Python, it's nowhere near the most challenging.


How difficult is it to find good JavaScript developers?

Since JavaScript has been around for some time, it's quite a common language among developers. And because JavaScript is so widely used by companies around the globe, you can be sure that JavaScript is used on a vast majority of websites. 

This, however, means that experienced JavaScript developers are in very high demand, so finding the best candidate can be a challenge. You must also take into consideration that, because of the skyrocketing demand for JavaScript developers, hiring the best of the best will come at a price. If you're serious about bringing your website up to modern standards, that should be a price you're willing to pay.


How to choose a JavaScript developer for your project

When scouting for a new JavaScript developer, you should make sure they have the following qualities:

  • They're experts with the language.
  • They have experience with the most popular JavaScript frameworks.
  • They understand JSON, jQuery, and Handlebars.
  • They have a solid grasp of Responsive Web Design.
  • They are passionate about the language and willing to continue their education.
  • They can follow standards.

Conclusion

To find the best JavaScript developers, you should take the time and carefully comb through the candidates. Make sure those at the top of the list are not only qualified for the task at hand but can work with a team and are adaptable when those inevitable changes in a project do arise.
