In 2011 a group of programmers started a project called Red. They were attempting to crete a so called full stack language. One language for web development, coding, applications right down to microprocessors.
They so wanted their language to be homioiconic, weakly typed and friendly to beginners. 3 years and a lot of work gave produced a language that's insightful and in depth, redefining the way we may program. They are still far from done though.
So, a full stack language is akin to the One Ring in Lord Of The Rings.
There are a ton of development tools like Yeoman and Mean to help you take care of stuff.
So now we have a large part of the stack running with JS but its not yet Full Stack as per Red's definition
