Background: Prior toffb6b2f, there was a bug in `URL_REGEXP`, trying to match the hostname as `\S+` (meaning any non-space character). This resulted in never actually validating the structure of the URL (e.g. segments such as port, path, query, fragment). Thenffb6b2fand subsequentlye4bb838fixed that bug, but revealed `URL_REGEXP`'s "strictness" wrt certain parts of the URL. Since browsers are too lenient when it comes to URL validation anyway, it doesn't make sense for Angular to be much stricter, so this commit relaxes the "strictness" of `URL_REGEXP`, focusing more on the general structure, than on the specific characters allowed in each segment. Note 1: `URL_REGEXP` still seems to be stricter than browsers in some cases. Note 2: Browsers don't always agree on what is a valid URL and what isn't. Fixes #13528 Closes #13544
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. Best of all?? It makes development fun!
