Two JavaScript Points

[MartinRinehart]

1. Hereabouts I once said that window.event is the same as event in a browser, because window is the global object. That was almost right.

This will get a cross-browser event:

onSomeEvent( e ) {
e = e || event;

MSIE, and I don't have it pinned down yet, sometimes insists on the window. prefix. I've started to routinely include window. even though it looks pretty dumb.

2. Pop Quiz!

var arr = [1,2,3,4,5];
for ( elem in arr ) { alert(elem); }

What is the first elem?

Dan, if you know the answer, please be a little slow to post it.
