Just because it is the dominant paradigm doesn't mean it is a good paradigm.
Remember PHP was a dominant paradigm for a long time. (I actually don't dislike PHP that much myself but it is a good example since many dislike it intensely.)
Edit: JS, until TypeScript, had almost all the disadvantages of PHP (bug prone syntax, lack of typing, inconsistent ordering of method parameters etc) but not PHPs advantages (shared nothing, fast dev cycle). The only advantages JS had was that it looked cleaner and that one could use the same language frontend and backend.
