Why is masterList cached in a local var?

Hi all,

 

This is more of a technical question, but anyways. I noticed that the "masterList" Dictionary object is cached in a local var before iterating through it. Why is this? Is there any speed benefit?

 

var ml:Dictionary = masterList;
var tgt:Object;
for (tgt in ml) {

 

I was just curious if this was needed.

 

Thanks.

Yep, local variables are accessed faster.

Strange. I never knew local object vars are accessed faster. You must have near-infinite energy Jack! Half the project owners I know would have stopped answering my questions at this point!

 

Thanks a lot!
