Easiest way to check if string is null or empty

Question

I\'ve got this code that checks for the empty or null string. It\'s working in testing.

eitherStringEmpty= (email, password) ->
  emailEmpty = not email? or          


        

Answer 1

If you need to check that the content is a string, not null and not an array, use a simple typeof comparison:

 if typeof email isnt "string"
