> learn both This is a common advice but it isn't realistic. It takes a lot of time to learn a language, its tools, its most popular libraries, its best practices, to interact with its community, to see in what problem domains it shines, etc. I'd say you need to give it more than a year, more than two if you're not doing it on the job. You can churn code much sooner than that obviously, that's not what we are taking about. Nobody does that to see which language is best. And those that do are doing it superficially, writing a hello world or two and then jumping to conclusions. This advice basically makes no sense and yet people keep repeating it.
