I personally am a fan of Python lately. Of course, that's mainly for quickly coding things. You then rewrite what you need to to be faster or more efficient. But it doesn't really matter what language you program something in anymore, as long as you optimize it properly and rewrite any parts you need to in a lower level language like C/C++, or hell, even Fortran.

I just hate Java and JavaScript with a passion because I was learning web dev and trying to get more into programming when Java started to become a things and Javascript was mainly used for making little floating color things that followed the mouse. Dynamic webpages only started to become a thing after I was already perusing the computer book aisles pretty much every other day. Because of being exposed to it that far back, when it was all fairly new, I basically knew them as a nightmare to work with. They were very ugly and hard to use back then. JavaScript was actually far better. It was ugly as hell, but it wasn't that hard to do cool things with it. I actually never even figured out how to package the Java apps back then. It wasn't so easy at first. There were these jar apps that you had to do something with. I don't even remember. But I remember trying to figure it out for at least a few hours. Guess I wasn't motivated enough though.

I remember I painstakingly replicated the Mac OS X doc for a web page using JavaScript though. Still annoyed that no one was really impressed. That took me more than a few hours. Wasn't quite as smooth on a webpage, but it was pretty cool.
