Angular is an open-source web application framework led by the Angular Team at Google and by a community of individuals and corporations. It is a complete rewrite from the same team that built AngularJS. Angular was officially released on the 14th of September 2016.

Angular is a component-based framework which uses declarative HTML templates. At build time, transparently to developers, the framework's compiler translates the templates to optimized JavaScript instructions. Angular uses TypeScript, a superset of JavaScript that we'll look at in a little more detail in the next chapter.
