Javascript Development Services

Clevertech is committed to using JavaScript as a foundation for all of our applications. Here's why that's good for our customers.

Google has made a massive investment in JavaScript—through their development of the V8 search engine, an Open Source search platform based in JavaScript and fueling Google-based browsers like Safari and Chrome.

For visitors using Google browsers, your application or website will perform much faster than competitor sites that aren't based in JavaScript. This works in your favor, because online, speed wins. Visitors won't stick around if your competitor's site is performing slowly—they'll click over to yours, and notice the difference.

Adding interactive functionalities to a webpage can greatly improve the user's experience, and that's when JavaScript development comes in handy.

Our developers rely on extensive JavaScript expertise to develop strongly intuitive user interfaces and fast applications for our clients. Our comprehensive Backbone.js, Rafaël, and jQuery libraries let us speed up our development process—and get our client projects up and running in 30 days or less. We have written JavaScript code to accomplish everything from simple rollover effects to complex CSS manipulations.

Our team members are major contributors to Open Source libraries for JavaScript—and we stay on the cutting edge of advances in technology. As our client, you'll take advantage of our expertise in leveraging HTML5 to develop outstanding software for the desktop, laptop, and mobile device—that your end users can access with or without an Internet connection.
