i've used javascript for single page apps (i.e. real time trading) in early 00's even before the advent of great frameworks such as jQuery.. and it worked really well! at no point did i hear anyone say "i wish javascript wasn't so limited". it's just a vary playable language that's easy to learn and quick to use to hack things (or create entire frameworks out of). it's no coincidence that it's still so popular.
