As a C++ head I rarely see syntax like the above and I find it quite
difficult to parse. I've seen stuff like that when reading jQuery.js and
code that uses it, but what is actually happening and why is it such a
common construct when using javascript? Got links?
It looks like a unnamed function is defined 'inline' inside some (), like a
python lambda function or so, and then called immediately. Is that what's
happening?
All the best,
Steve.
