What happens when this code is executed with DevTools closed?
function calculateTotal(items) {
debugger;
let total = 0;
for (let i = 0; i < items.length; i++) {
total += items[i].price;
}
return total;
}
The debugger statement's behavior depends on the debugging environment: 1) When DevTools are closed, the statement is simply ignored, 2) Code execution continues normally without any interruption, 3) No performance impact occurs in production environments, 4) Acts as a no-operation instruction when no debugger is attached, 5) Safe to leave in production code though not recommended, 6) Provides zero-overhead debugging capability, 7) Won't affect end users who don't have DevTools open, 8) Allows for development-time debugging without production impact.
