Edit Question
Title
Body
I want to guard my functions against null-ish values and only continue if there is "defined" value. After looking around the solutions suggested to double equal to undefined: if (something == undefined) . The problem with this solution is that you can declare an undefined variable. So my current solution is to check for null if(something == null) which implicetly checks for undefined. And if I want to catch addionalty falsy values I check if(something) . See tests here: http://jsfiddle.net/AV47T/2/ Now am I missing something here? Matthias
