[webkit-dev] Data Structure built during JavaScript execution

[Lucius Fox]

Hi,

Can you please tell me what is the data Structure built by Webkit
during JavaScript execution?
For example,

var a = 1;

function b() {
  alert('hello");
}

It needs to build a data structure to save the value of a inside the
VM.  Can you please tell me what is that defined?
same as Function, how is that being maintained inside javascript VM.

Thank you.
