How AngularJS was born

AngularJS started as an internal Google project by Misko Hevery, sometime in 2009. As the story goes, Misko's team was working on a project called Google Feedback; even after six months of development and about 17,000 lines of code, they were still unhappy with the pace of development and the inability to write automated tests. That's when Misko decided to rewrite that. It took him about 3 weeks and he managed to write the whole thing in just about 1,500 lines of code.

That's when AngularJS got some serious attention internally at Google, and a team was put together to help further develop it. Around 2010, Google decided to declare it as open source under the MIT license.
