Get everything in a string before hyphen in Javascript

I have a dynamic string value which includes language and country code. I need to extract the value before hyphen and store it in a variable. How can I do this? I don't know how many characters will be there before the hyphen. I cannot use substring(). Note: I know how to extract after hyphen using split(). I need to get before value.

mystr = "eng-can";    Output:  extactedstr = "eng"
