Does anyone have recommendations for languages that are important to learn for web development? I'm thinking of an ecommerce platform currently. Also, is codeacademy something y'all would recommend, or is there something else I should take a look at?
If you want something more versatile (for non-web programming), I would suggest python.
If you go with python, Django is the most popular web framework. However, I find Flask much easier to get started with.
Both are excellent languages. It is tempting to spend a lot of time researching the options in the hopes of picking the "best" language. In my experience, it's better just to pick one and get down to work.
Don't forget that you're also going to want to know javascript for your front-end development.
I suspect node.js is going to come on strong over the next few years, but in most discussions I've been having recently, everybody I've spoken to still feels it's a bit to early to jump on that bandwagon. But if you want to get ahead of the curve, node might be the ticket.
