I understand 37. Because octal. I know that parseInt takes an optional radix argument. My only question is, why is Alfresco Javascript different?

I think it has something todo with JavaScript engine. Different engine treats parseInt('045') differently.
Alfreso use Rhino as JavaScript engine,using Rhino to evalute parseInt('045') will give you 37.
