Press the J key to make the astronaut jump
A LOOP is a repeated activity. Two loops are used to make the astronaut jump up and down. I DECOMPOSED the idea of a jump this way: 1) The astronaut will jump when a key is pressed (EVENT) 2) she must move upwards ...and this is repeated little moves upwards to show her moving (not just shifting to a higher location) 3) then she must move downwards ...again little by little
