Pointing out errors

[neuronetio]

I know it will be a lot of work but it would be great if it could point out errors in js.
It would be great to know where we screwed up (because otherwise we have to think and guess for a long time). We waste a lot of time on it - and we want to test something quickly, so it's a bit annoying.
So pointing out errors would be a great feature.

Even if the errors were displayed in the console, that would help a lot.
Or maybe try catch and somehow parse what we got?
Since the application knows that there was an error, it's probably possible to do something with it and display it somehow (I'm guessing).
