How to raise error in Javascripts Katas?

[jotakar]

Some katas ask for throw an error in some situations, but I've tried to use try...catch, and trow new Error() and it doesn' work. And I van not find any help in docs. So how can I raise errors in katas? (Javascript)

Maybe try using `throw new Error('some error message')` without try / catch blocks. You just have to throw the error from within the function; the tests will catch it accordingly (as long as the thrown error is expected from the tests).

Finally I got it. I wrote throw true, without try catch.

The way of signaling an error might depend on a kata, so it would be better to ask in discourse of a specific kata.

What seems suspicious is that a kata asks you to raise an error, but for some reason you went with try/catch what is an exact opposite of the task (try and catch are used to handle an error, and not to raise it). try and catch should not be necessary in solution (but again, it depends on what exactly kata wants you to do).
