All of the below properties or methods, when requested/called in JavaScript, will trigger the browser to synchronously calculate the style and layout*. This is also called reflow or layout thrashing, and is common performance bottleneck.
Generally, all APIs that synchronously provide layout metrics will trigger forced reflow / layout. Read on for additional cases and details.

The Scope class regulates lexical scoping within CoffeeScript. As you
generate code, you create a tree of scopes in the same shape as the nested
function bodies. Each scope knows about the variables declared within it,
and has a reference to its parent enclosing scope. In this way, we know which
variables are new and need to be declared with var, and which are shared
with the outside.

In the year since 1.0 was released, there have been 10,000,000+ visits to phonegap.com, and 1,000,000+ downloads of the phonegap software. build.phonegap.com, the automated build service (so you don't have to compile all the different targets yourself) has 100,000 users, and is due for a formal release "soon."
Regarding naming confusion, "Cordova" is the Open Source project, owned by the Apache foundation, and "PhoneGap" is Adobe's distribution. (Just like "Linux" is the core Open Source project, and "Ubuntu" is a distribution of it.)
