Do you need a JavaScript developer for your project?

JavaScript is a programming language built primarily for web development. On web pages, it is responsible for interactive elements and animations, like search bars or video players. JavaScript is a text-based language, responsible for those parts of a web application which are crucial to the functionality.

It was first made available in 1997, and it’s a relatively simple, and very useful language. When it was first introduced, server costs were much higher, so JavaScript was revolutionary because it reduced server traffic (with client-side code execution), and in doing so, reduced financial costs as well.

For the users, widespread implementation of JavaScript allows highly responsive web applications, and a convenient, pleasurable user experience.

Along with HTML and CSS it is the fundamental programming language of web development. It performs dynamic tasks within web pages. All popular browsers have built-in support for JavaScript.

JavaScript code is very reusable, there are a lot of readymade scripts which can be added to a website by simply copying and pasting a few lines of code. It is fast, as browser run it almost immediately. It doesn’t get involved in network calls to a server, and it doesn’t have to be precompiled which gives it more speed.

Which is great, however it creates a problem. Client-side JavaScript code is executed on the user’s machine, not on the app’s back-end server, which means that hackers might be able to take advantage of it (which is why people sometimes disable JavaScript support in their browsers).

Another common complaint with client-side JavaScript is that behaviour across browsers can often be unpredictable, however there are testing tools out there which make it easier to make scripts that work the same across different browsers.

That’s just client-side JavaScript, responsible only for the front-end part of a web app. By extending its capabilities with powerful frameworks and libraries, developers can use JavaScript to build complete web applications – both the back-end, and the front-end.

There are many different applications for JavaScript which have been made possible thanks to various frameworks and libraries like Angular, Node.js or React.js.

JavaScript has been growing in popularity a lot. It may be partly because it is a flexible language that integrates well with other languages, and it can be used across a very wide range of applications like, for instance, using it inside scripts written in languages like Perl or PHP.

What skills should JavaScript developers have?

Looking for a JavaScript developer can mean three things:

  • One: it means looking for an all-around front-end developer who will be responsible for the looks of a web application.
  • Two: the project requirements include JavaScript server-side development environment Node.js, and the JavaScript developer is supposed to work on the back-end.
  • Three: the project needs an all-around JavaScript magician who can do both server- and client-side development.

Good all-around JavaScript developers should have a solid, flawless understanding of HTML and CSS, as well as JavaScript itself. Experience with CSS preprocessors like Sass and LESS can come in handy.

JavaScript developers should be familiar with multiple JS frameworks. The most important ones include Angular, React.JS, and Ember. Another important thing are JS-based build tools, like Grunt, Gulp, or Bower.

AJAX is a good skill to have for JavaScript developers, as well as Express.JS, and Horizon, which are all good additions to the developer’s skillset.

A good, full-stack JavaScript developer might have their favorite technology stack for building entire applications with JS, for instance MEAN (MongoDB / Express.js / Angular / Node.js).
