What I've found to be the most efficient way of learning new programming languages..is not by using it. While is it true that you need to use it to gain mastery. It is best to learn new language as simply as a programming language. That means studying its features rather than syntax and grammar. Is the language object oriented, functional,or multi paradigm? The point being that syntax and grammar changes all the time from languages to languages, but programming paradigm rarely changes. Truly grasping the idea of a programming paradigm will make you learn new language a lot faster..and new programming languages emerge almost every year.
