In 2005 the term Ajax was coined by Jesse James Garnett, founder of Adaptive Path, in his published white paper explaining usage of JS as a backbone technology for creating dynamic web applications. This leads to an explosion of usage and the creation of several very popular community libraries such as jQuery, Mootools, and Prototype. Indeed, it is truly a community driven language and because of that, there is no shortage of developer talent.
Where the Libraries started the Frameworks followed, including one of the most popular and fundamentally important -Node.JS. It was created in 2009 by Ryan Dahl and others at Joyent. Node.JS marked an important step forward for the scripting language, turning it essentially into one of the first modern complete programming languages, able to excel in frontend and backend roles.
