If you change line 10, it will not connect, and thus the while-loop will only stop when the timeout runs out and it gives up.
It works by attempting to call wifi.connect(...), then waiting for a while (determined by the timeout parameter), if the time passes and it hasn't connected it will time out and call wifi.disconnect()
This was written as part of an educational initiative, and is not at all production level code, and shouldn't be used for anything but small non-important projects.
