Made the example shown consistent with the advice above it regarding not using `select as` and `track by` in the same comprehension expression. Also changed references to `trackexpr` to `track by` since `trackexpr` is not defined except in the examples. Added filter + track by example for ngOptions The documentation for ngRepeat includes such an example specifying the proper order for filters and and "track by" clauses in the comprehension expression, but these docs for ngOptions do not.
AngularJS 
AngularJS lets you write client-side web applications as if you had a smarter browser. It lets you use good old HTML (or HAML, Jade and friends!) as your template language and lets you extend HTML’s syntax to express your application’s components clearly and succinctly. It automatically synchronizes data from your UI (view) with your JavaScript objects (model) through 2-way data binding. To help you structure your application better and make it easy to test, AngularJS teaches the browser how to do dependency injection and inversion of control.
Oh yeah and it helps with server-side communication, taming async callbacks with promises and deferreds. It also makes client-side navigation and deeplinking with hashbang urls or HTML5 pushState a piece of cake. The best of all: it makes development fun!
