JavaScript developers are empowered with the tools to make the internet dynamic and flexible. In other words, they use JavaScript to build web apps and websites with interactive content.

The invention of JavaScript was and continues to be a game-changer for front-end development. Whether or not you realize it, JavaScript developers are essential to the way you perceive the web today.

Thinking of hiring JavaScript developers? Well, you’ve come to the right place. Keep reading!

What Is a JavaScript Developer?

A JavaScript developer is a type of software developer. JavaScript itself is a programming language that does wonders in the realm of web development.

JavaScript is a scripting language for web developers to turn static content into live, moving pieces. That is, the minute interactions of a web page you see today, from scrolling bars to mouse clicks, are indebted to JavaScript. 

Since JavaScript’s 1995 inception, you can find the language working hard on the front-end of web development often alongside CSS and HTML.

What Does a JavaScript Developer Do?

The 2019 HackerRank Developer Skills Report found that nearly three-fourths of developers had proficiency in JavaScript. It goes without saying that JavaScript is a popular programming language.

With this many developers using JavaScript, there must be a good reason for it. So what does a JavaScript developer do?

JavaScript developers typically work on the front-end of web development. That said, the use of JavaScript is not limited to front-end development, meaning JavaScript developers can work on the back-end too.

Node.js, for example, employs JavaScript on the back-end. By using Node.js, developers can better utilize JavaScript’s ‘write once, run anywhere’ paradigm by deploying the language on the front and back-end simultaneously.

The day-to-day responsibilities of a JavaScript developer might include:

  • using HTML/CSS to design the structure of a web page
  • building user interfaces (UI) that correlate with user behavior in an intuitive way
  • coding software applications that adhere to project requirements
  • overseeing testing and finding bottlenecks in code

To do their jobs effectively, JavaScript developers must have a number of skills. 

The skills JavaScript developers need to do their job efficiently involve an array of different front-end development tools. First and foremost, all JavaScript developers should be familiar with CSS and HTML.

HTML, or HyperText Markup Language, is a standard markup language for organizing web content on a page. It essentially allowed developers to present documents and/or text through a web browser.

CSS, or Cascading Style Sheets, is another fundamental building block of a web page. This determines the style and/or layout of the page. Fonts, colors, and spacing among other things are all determined by CSS.

These technologies play a heaping and helping hand in building front-end technology alongside JavaScript.

In addition to being sufficiently familiar with JavaScript, CSS, and HTML, JavaScript developers should also have familiarity with the many frameworks that promote ease of development for JavaScript applications. 

How Much Does It Cost to Hire a JavaScript Developer?

JavaScript developers make over $100K US dollars on average per year. 

JavaScript developers in the United States will make an average salary of $113,115,

on the authority of ZipRecruiter records as of March 2020. If you want to pay your developer an hourly salary, that’s the equivalent of $54 an hour.

JavaScript developers making the highest salaries earn $168,000. Those making the lowest salaries make $41,500. Typically, salaries are based on experience and expertise.

Outsourcing developers from outside the United States will guarantee less expensive pricing. However, doing this means language barriers and time zone differences will become greater concerns. That said, nearshore development can provide the best of both worlds.

How to Hire the Right JavaScript Developer?

Hiring the right JavaScript developer requires considerable familiarity with the in and outs of the language.

To ensure that you’re hiring a developer that can meet the requirements of your project, it almost goes without saying that you must have a pretty good idea of what those requirements are and how they should be met.
