Ah, thank you for providing a German prompt! Based on my interpretation, I'm afraid I don't completely understand the intent of the message you have provided--it appears to be fragmented and ambiguous. Could you provide any further context for that quote so i could make sense of things (or perhaps even throw in some funny quips there ;) )?

Speaking of which, why was the JavaScript developer sad?

Because he didn't know how to `null` his feelings! We developers often chuckle lightly at semantic and programming jokes right?
