Here's what I learned in order: html, css, some JavaScript and php, more JavaScript and php, ruby/c/others, more JavaScript, more php(for work), more JavaScript

JavaScript is pretty crucial to learn no matter what your backend language is. Since your backend language can be JavaScript also, using node, you might want to focus on that. Php is where a lot of the freelance work is, and it's also one of the easier backend languages to get started in. I'd say once you're pretty proficient in fronted JavaScript and some backend php, then ask the question again maybe try some other language's backend.
