C
very good for systems programming but easy to misuse
C++
potentially allows you to write more readable C but most devs use it to write labirynthine abominations
Go
has potential
Rust
shit
PHP
it's so hackish and kludgy it makes C look well designed. most of people who develop in it are idiots
Perl
good for getting shit done
Ruby
see above, I guess; not sure why use it instead of Perl
Python
also good for getting shit done
Javascript
shit for anything serious but its ubiquity combined with endless ways you can fuck with the code has many fun security implications (see JSFuck for example)
Lisp
I'm not good at functional but I find it interesting so I'd like to learn it one day. also
LainScheme
not sure why would I use it instead of Lisp
OCaml
it's a mess
Haskell
looks elegant so I like it
