Error handling with promises by mahdiHash · Pull Request #224 · javascript-tutorial/fa.javascript.info

"Unhandled" has to be translated since I've translated the word "handle" everywhere. The problem is with "rejection". In this article I didn't translate the words "reject" and "resolve". IMO they're better to be left as is, so, "rejection" can be "rejection". But I like to have your opinion on it, too.

P.S. I want to change the translation of some words in the vocabulary of README. This change will keep them in English (not translated).
