I like using codewars.com for learning new languages. Just pick a language and start running through problems. I think the best part about it is that you can review other solutions after you solve the problem. Usually there are some really clever solutions that show off the features of the language, as well as clearer solutions that are a bit more idiomatic to the language and more in line with what you'd want to commit to production. For learning frameworks I usually just refer to the framework documentation and source code.
