**Knockout** is a JavaScript [MVVM](http://en.wikipedia.org/wiki/Model_View_ViewModel) (a modern variant of MVC) library that makes it easier to create rich, desktop-like user interfaces with JavaScript and HTML. It uses *observers* to make your UI automatically stay in sync with an underlying data model, along with a powerful and extensible set of *declarative bindings* to enable productive development.
|
||||
|
||||
## SnappyMail Modifications
|
||||
|
||||
Knockout has a high level of backward compatibility. We don't use it, so a lot of IE code is stripped.
|
||||
|
||||
npm closure-compiler is old and broken for ES2015/ES6, so we use the new google-closure-compiler.
