What our customers are saying


At a Glance: JavaScript Development

JavaScript (JS) is a cutting-edge front-end scripting language that’s used to create user experience, interactive webpages, and responsive front-end design while also functioning as a server-side script, thanks to breakthrough development environments like Node.js. All user experience and interactivity is driven by JavaScript, but the language can also power a full-stack JavaScript site with the MEAN software stack. Anything a user clicks, edits, inputs, or pulls up on a website is possible thanks to JavaScript, so it’s a must in the toolbox of a front-end developer. This versatile programming language is used in tandem with client-side technologies like AJAX, responsive web design, libraries like jQuery, and numerous frameworks like AngularJS, ExpressJS, BackboneJS, and Bootstrap to create fast, responsive, mobile-friendly websites and applications.

In addition to building and maintaining the front end of your website, a JavaScript developer can build server-side JS applications with the Node.js development platform, the Express.js framework, and MongoDB databases. JavaScript developers on Upwork have experience with the JavaScript landscape of technologies and are masters of front-end workflow management, site testing, and user experience.
