Short Circuit Evaluation

When you upgrade from basic Halloween logic to enterprise-level conditional execution. The top panel shows the casual "treat or trick" approach—simple, readable, something your product manager might understand. But then we suit up with treat||trick(), where the compiler's like "already got the treat? Cool, not even gonna bother calling that trick() function."

Short-circuit evaluation means the second operand only gets evaluated if the first one doesn't seal the deal. It's lazy evaluation at its finest—why do more work when you can do less? Your CPU thanks you, your function calls thank you, and that potentially expensive trick() function that might've queried a database or summoned a demon? Yeah, it's just chilling, never executed. Efficiency dressed in a tuxedo.
