I recently came across this article: https://news.ycombinator.com/item?id=123903 and this was posted almost 7 years ago.Most people here suggest Perl/Ruby/Python.
I have recently started to learn MEAN stack, and I don't know if I am on the right track.
What is the best combination of frameworks/languages that you can use for webD, as of today?
Once you learn Python, it's much easier to learn JavaScript and/or Ruby.
Note: I am co-founder of Real Python (https://realpython.com), which teaches the Python syntax and web development through real world examples.
I also teach at a full-stack JavaScript bootcamp - http://www.refactoru.com/ - and am a mentor through https://www.thinkful.com/ in Angular, Node, and Python.
Feel free to reach out with more questions - michael at realpython dot com.
Cheers!
