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.

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

What Are the Skills Needed for JavaScript Developers?

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.
