JavaScript is a programming language that is used across almost the entirety of software development, from front-end engineering to mobile development and even for game development. It is so popular, in fact, that it continues to be the most commonly used programming language, according to the annual Stack Overflow survey; 2022 marks its 10th year in the top spot.
JS, as JavaScript is often abbreviated, is used on a majority of websites, up to 98% actually. Just about any visit you make online will involve JavaScript, a language that traces its origins back to the mid-90s and the once-great Netscape company, makers also of the now-defunct Netscape browser.
JavaScript is quite versatile, but it is most often used to add dynamic content and features to otherwise static web pages. It is regularly used for calling APIs to serve fresh content, storing values, manipulating data, and a whole lot more.
Every modern web browser includes a JS engine to parse code, but there are also runtime environments such as Node.js. JavaScript frameworks help software developers by offering “building blocks” of pre-built code to use for routine tasks.
Because of its ubiquity and necessity in just about everything we do nowadays, particularly online, you’re probably going to be using it for your project. So, whether you choose a JavaScript freelance developer or not, you’ll likely need a developer who’s well-versed in JS.
The length of a project depends on many factors, including the scope of your project and the technical complexity of it. When you post a freelance JavaScript project request on Codementor, you’ll have the option to indicate when you’d expect the project to be completed. We suggest chatting with the interested developers to ensure both sides are on the same page. For more information on how to post a freelance JavaScript request on Codementor, check out our article.
We don’t charge anything when you post a freelance hiring request for JavaScript developers! You’ll have the chance to determine what the budget for your project is when you post the request. You’ll only need to pay the developer if you’re 100% satisfied with their work. Please know that Codementor charges a small service fee when a developer completes the job.
When hiring a freelance JS developer, consider the depth of their JavaScript knowledge. If you will require them to work with JavaScript almost exclusively, they’ll need a good understanding of the entire ecosystem, with some knowledge of React, Angular, Node, jQuery, Typescript, and other technologies. If you’re looking for a good well-rounded developer, you may choose someone with less depth in JavaScript but more breadth across other areas of engineering.
Aside from technical skills, be sure your prospective freelance JavaScript programmer has the soft skills to be a good fit, as well. Every solid coder you hire should be a great analytical thinker, problem solver, and decision maker. Plus, you’ll want to check to see if they have the experience and abilities to work well with you and your team as a remote hire.
We do a comprehensive technical and communications screen of all JavaScript developers at Codementor. Our network includes book authors, popular open source contributors, top Stack Overflow users and engineers at top tech companies. In addition, to continually ensure the quality of our freelancers, we regularly check in on existing JavaScript developers’ user satisfaction rates.
On the technical side of things, ask questions about JavaScript and any other technologies you may want them to utilize, of course. However, dig a little deeper with your questions. Use your interview questions to understand how they go about solving problems and what their thought process is like.
Ask questions to delve further into their soft skills and remote abilities, too. Use the interview to get a sense of how well they communicate, and try to work out how well they’d do managing their own time and staying organized, as well.
