Personally I have found that this is relevant only for front end work. For the backend you just need rudimentary knowledge of a framework/language to get your foot in the door, then the actual testing is language agnostic.

Makes sense. Us front end guys are fairly expendable.

Don't pigeonhole yourself into the frontend. Be language agnostic. Mastering the fundamentals allows you to transition across the stack.
