not sure about javascript. But in c++ it looks like this switch(expression) <- this is evaluated once. { ~~ } So if we had int x; cin >> x; switch(1+x) { }; The expression 1+ x would be performed or calculated just the one time. The result is stored and used to compare against the case statements. I assume javascript switch statements operate in a similar way
