Why doesn’t my loop break when parcels.lenght === 0 ?
function completeRoute(start) {
let at = start;
pickUpParcels(at);
for (let turns = 0; ; turns++) {
console.log("turns = " + turns);
console.log("pickedUp length for loop " + pickedUp.lenght);
console.log("parcels length for loop " + parcels.length);
if (parcels.lenght === 0) {
console.log(`Delivered in ${turns} turns`);
break;
}
console.log("dest lenght = " + destination.length);
if (destination.length === 0) getDestination();
//console.log("destination " + destination);
getRoute(at, destination[0]);
console.log("route " + destination[0]);
move(at, destination[0]);
at = destination[0]
destination.shift();
}
}
completeRoute("Post Office");
As you can see parcels.lenght hits zero but the loop continues.

Secondary question, why is pickedUp.length undefined within function completeRoute when it is not undefined elsewhere in the code?
