Conditionals and Loops


“I taught myself how to program computers when I was a kid, bought my first computer when I was 10, and sold my first commercial program when I was 12.” - Elon Musk

WHAT'S IT ALL ABOUT?

When computers run a program they need to follow commands. A command that uses a conditional statement uses the word “if”. In a Loop, a code block is followed until some condition is met. When a computer sees these codes, it follows the commands if they are true and stops when they are false. For example, when you are playing a game, and the player jumps when you hit the spacebar, that is a conditional: - if(player.pressSpacebar), then { player.jump(); }.

TRY THIS

Play a game like Simon Says with a friend or family member. They are your Computers and you are the Programmer. Make it complex by using Conditionals or Loops. You could say, “If I raise my left hand, you raise your right hand” (a conditional) or “While I am jumping, you are clapping.” ( a Loop) Then try to build onto that with more statements and see how many you all can remember. Try starting with five statements for one game and then add on more.
