[JSMentors] Memory Leaks

[Adrian Olaru]

Hi guys,

I have this code:

var a;

function init() {
  a = new SomeObject("one");
  a.doSomething();

  a = new SomeObject("two");
  a.doSomething();
}

init();
a = null;

What happens with the first object created and assigned to a? It's this an
example of memory leaking, or will be garbage collected?

Now, I know about garbage collection and how is implemented in browser
(mark-and-sweep vs ref count (ie) ), but still, I wanna be sure.

Thanks.
