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

Here is a jsfiddle demonstrating a very easy way of doing this.

Basicly you simply do this is javascript:

var email="oranste";
var password="i";

if(!(email && password)){
    alert("One or both not set");        
}
else{
    alert("Both set");   
}

In coffescript:

email = "oranste"
password = "i"
unless email and password
  alert "One or both not set"
else
  alert "Both set"

Hope this helps someone :)
