Languages I know fairly well
I type on this nearly everyday for work. And Rails is so easy to me now. It's still what I reach for first when putting together a new project. The speed at which I can get something going with ruby and rails is, well fast.
JS is like English, the language franca of the web, which is there I do 90% of my programing for in some way or another.
Frameworks I know well
Ruby on Rails
Languages I know moderately well
Functional languages make me think about programming differently, may I say, better. I like to organize my code more as a data manipulation than as objects, it just makes more sense to me.
Languages I'm interested in learning (in order)
The ability to package up a single binary is nice, it's like go but better for me because I know ruby. Static typed, compiled, fast.
To broaden my horizons really, and think more about memory management.
For most of the same reasons as crystal but with a couple interesting language features like its generics and method overloading.
Frameworks I'm interested in learning
Amber - Crystal
Because of its pure speed.
Likes like a nice fresh take on frontend frameworks, I like the idea of the framework being more like a compiler. We usually have a build step in the front end anyways.
Its fault tolerant nature would make me happy to deploy code that is meant to stay up for a long time, or code that need to run many concurrent connections at once.
This is like my goto instead of jQuery these days possibly. It's such a nice framework.
Frameworks I have used
Angular 1 and 2
