JavaScript online coding tests aren't hard to create, There are almost 1.6 billion total websites in the world, and out of which 1.52 billion websites use JavaScript. That’s 95% of the total websites! It’s the true programming language of front-end engineering and the underlying language that ties everything together. 

JavaScript is a runtime language for web browsers. This means when you open a web page, the page will load both the foundational JavaScript, which is standard with the page, and any new JavaScript added to a page. The new JavaScript will load in parallel with foundational JavaScript and can perform actions and make decisions.  

According to a survey conducted by Stack Overflow, JavaScript has maintained its stronghold as the most commonly used programming language (eight years in a row!) 

Skills JavaScript Developers must have: 

JavaScript developers are responsible for ensuring UI/UX feasibility, optimizing applications, and implementing architecture and API designs. It is the responsibility of the developer to understand the need for a scripting language and frontend platform-related duties. 

A good JavaScript Developer must be ready to perform in a fast-paced environment and implement complex design specifications in the least amount of time. So, besides having an in-depth understanding of JavaScript, an ideal candidate should have the following skills as well: 

  • HTML, CSS, and JavaScript: These will be needed to build dynamic websites or web applications. 
  • React, Angular, or Vue: These are part of JavaScript libraries and frameworks, and are used for building user interfaces.  
  • Knowledge of web markup, including HTML5 and CSS3. 
  • Proficiency with jQuery (“write less - do more” JS library) and Bootstrap frameworks. 

How can you hire the best JavaScript developer for your team 

Despite the popularity of JavaScript among developers, finding the right JavaScript developer, who not only matches the skills required but is also culture-fit, can take some searching.

Begin by determining what sort of JavaScript developer you need in order to narrow down your quest and save time for both you and your candidates. 

From there, you can construct the hiring and evaluation process to assess your candidates on all of the important parameters we discussed in the last part. This process will not only serve you in finding the ideal JavaScript developer for your team, but it will also serve you in doing so swiftly, giving you confidence that you are making the right choices at every step of the way. 

Some Quick Do's and Don’ts to Hire JavaScript Developers

  • Do test your candidate's skill early 
    Consider screening your applicants' knowledge through a JavaScript online coding test before the screening process. A number of organizations mandate a quick assessment when they submit the application as well. This way, you won't have to go through unqualified applications and you'll save time.
  • Do choose a candidate with good communication skills 
    JavaScript is a technically complex language, it is critical to find a developer who is also a good communicator. A JavaScript developer with good communication skills will be able to communicate their ideas, suggestions, and project progress in simple language that everyone can understand. 
  • Don't limit yourself to only technical questions. 
    In order to understand how your candidates' technical skills are applied in real-world situations, ask contextual and situational questions.
