JavaScript Regex for matching only first of two same characters in a string regex matching only numbers,regex matching only letters,regex matches

I have these two strings: "1-2" and "1--2".

I would like to have a regex that would match only the first occurrence of the hyphen in both strings, such that the split would then be: [1,2] and [1,-2]. How would I achieve this, since I have been wracking my brain for too long on this now?

EDIT: The two strings can also occur in the same string such that: "1-2-1--2". Therefore a single regular expression covering both cases would be in order.
