How to hire a great freelance Sencha / YahooUI Developer

At the beginning of the century, the situation of web development looked totally different from what it is now. Most desktop computers used Internet Explorer 6.0 and the first of versions of Firefox and Safari were coming into light. Internet connections were pretty slow, the websites were basic and not many people thought about creating interactive web applications. HTML 5, Google Chrome and iPhone was nowhere on the scene. With the introduction of JavaScript libraries like prototype and jQuery around 2006, web developers started to embrace JavaScript for more than simple web form validation and image rollovers.
The Yahoo User Interface or YUI was conceived in 2005 and was not for the public in the year 2006. Naturally, YUI became popular pretty quickly since the name Yahoo was attached to it. Moreover, it was the first JavaScript widget library which gave developers the power to make customized widgets that worked consistently across various types of browsers. This allowed web applications to duplicate many of the functionality of the native desktop applications.
If you are a programmer who needs an extra hand with using YUI, we suggest you to look online and higher freelancers for your needs.
