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!
