I don't do well with anything weakly typed except JS I guess, but there isn't much of a choice but to learn JS these days or rely on someone else who does know JS. I exclusively use typescript these days though.

Indents stink. {}; ftw. Python is fast to build with, I mean is practically a cross platform script, so I use it occasionally but don't like it.

Which brings me to yaml. I used to HATE yaml. Anything with yaml I would drop interest in the thing and leave it. But now I have grown to really like it, I'm adding a parser library to vnlib to accept yaml & json. It turns out what I hate is the documentation for yaml based apps. Most docs using yaml just plain suck.
