I've used or actively written in:
VB & VB.net
C#
(dabbled in) VC++
FoxPro (6 or 7 i think)
Objective-C
Swift
PHP
(dabbled in) Perl and Python
Javascript and various frameworks
FoxPro back in the day was just kinda... weird. In the capacity I used it, it was basically like web forms and SQL with little logic. Just seamed like a waste when VB(.net) or C# could do so much more against some other DB.
I think Objective-C syntax confused me the most. I could see it's similarities to other C based languages; just the specifics for NSObject / protocols / background tasks, just - seriously, @#$*@#$
I see similarities to Objective-C in Swift, but the syntax is much cleaner and I personally think it's a very elegant language; I've enjoyed writing in it so much, I'm considering running it on the server side instead of PHP.
PHP is and always will be home for me; I know others hate it; but for me, it's a swiss army knife. Tell me what you want me to build and I can get it done in an instant (relatively speaking) in PHP. If your not careful, you can produce very ugly code with it and reading others code is sometimes difficult, but it gets the job done when the jobs gotta get done, asap.
