I’m stuck on Stage #bw6
i dont get why this loop should terminate
for (var quz = 0; quz < 1; quz = quz + 1) {
print quz;
var quz = -1;
print quz;
}

Hey @m0lt0bene, there are actually two different variables named quz
.
The first one is declared in the loop header and is printed the first time:
for (var quz = 0; ...) {
print quz; // 0
The second one is declared inside the loop body and is printed the second time:
var quz = -1;
print quz; // -1
}
After the first iteration, the second quz
(the one inside the loop body) goes out of scope.
Then, quz = quz + 1
updates the original quz
from the loop header to 1. Since 1 < 1 is false, the loop ends.
Let me know if you’d like further clarification!
