It's just good to know. Don't jump on the bandwagon. Focus on the basic firsts, HTML, CSS and JavaScript. By having a good foundation rules than over knowing 10+ programming languages. Once you master a programming language, you can easily pick up other languages. Gotta keep an eye on the market as well.
Just doing some job trend comparison from March 2016 and March 2017. Slight % differences.
