It's not like you've been coding with Javascript and now you need to learn Haskell though. Companies love to sprinkle newest trends in their job ads with the technologies they used in their last 100 LOC pilot project and you discover in your first day that there are many big projects which use gulp, grunt and others with ES3, some without async support etc. I got a friend in Silicon Valley (I'm in Germany and here the attitude is more towards reliability and stability) and even there he got many interviews and a new job without listing many of the newest libraries/languages in professional capacity. Plus, I'd suggest you try Typescript with an open mind. It's amazing.
