Tim Sporcic:

JavaScript is rapidly maturing, and is finding itself at a similar stage as Ruby on Rails a few years back. As the lingua franca of the web, there is significant developer expertise, but the emphasis of the community is on putting in to place the practices and tools to not only build sophisticated solutions, but to also make them maintainable.

Great overview (even for wannabe developers like yours truly) by my friend Tim of how JavaScript is quickly maturing from a simple language for making stuff look cool on the web, to a full end to end stack that can manage everything.
