I came to Python for the GUI support, and I stayed because it is simple enough conceptually that humans can understand how it works.

I have written JavaScript as part of various JS frameworks, open source projects, and profesionally. As a MEAN stack developer, JS is my life. I would identify JS as the language I am most comfortable with at an advanced level. I also teach JS lessons in webinars from time to time. Please feel free to ask me any questions!

I find Scala to be both a beautiful and useable language. I like that you can use clear and concise functional paradigms, while still enjoying the benefits of object orientation and JVM interoperability.
