Back in the day when I was just learning to program, I wrote a BBcode library in JavaScript. Not knowing any better, I made very liberal use of globals throughout my code.
I later went to go port my code to PHP 4 (that was current at the time). To my surprise I was getting all these errors about how crappy of a programmer I was (both from globals and from misspellings and related problems).
I'm honestly not sure how people hate PHP so hard and yet don't mind JavaScript.
For me it was things like "function_returning_array()[0]" working in JS but not PHP and other unexpected parsing weirdness like that. (Though I don't really mind PHP, just much of the code written in it :-) )
