Yep, Javascript has a few warts.
* Implicit conversions. A problem common to many languages, so most
of us have learned to deal with it.
* The attempt to make semicolons optional was a failure and should
have been abandoned.
* Lack of block-scope. For some reason, it doesn't bother me in
Python, but it does in Javascript. That probably has something to do
with...
* Hoisting. Hoisting isn't intrinsically bad, but there's something
just a bit off about Javascript's hoisting. I can't quite put my
finger on why, but it trips me up.
* The == operator. It rarely does what you want. Just don't use it.
* When used in a browser, the rather odd meanings of 'this' in
certain situations.
I do like the use of closures.
And of course, the truly _great_ thing about Javascript is...
It's not PHP!
