Can somebody tell me what exactly += means and how exactly does it differ with =? I kinda get it by trial and error but I'm looking for more of a definition.
When I run this function with +=, the first and second div show up in a single alert box. So I know this is because I am using += but what exactly += telling the variable to become?
When I run this function only with =, then only the 2nd <class="span"> shows up and not the first <class="span"> Why didn't both fire sequentially as the .each function looped through the <class="span">?
[ps. I'm not too familiar with fiddlejs --> does that stuff stay up there forever?]
