If your objective is to build web apps, you won't get anywhere without knowing at least some Javascript. If you want to go server-side, I'd suggest Go.

That said: If you want to learn programming, just do it. Doesn't really matter what you choose now, at some point you'll think "Language X would come in handy now, I wish I'd learnt that instead". Resist the temptation to switch to something else, and stick with your choice for long enough that you can look at non-trivial projects and can sketch the implementation in your head and identity trouble spots. If you keep jumping between languages, you'll waste a ton of time learning syntax that could've been spent learning more about programming as a practice. Anyway, as you get more experienced, picking up new languages becomes easy (provided they're moderately similar to _something_ you already know) so there's not much pressure to do it right away.
