One thing that computers are really good at is repeating commands. As a person, you'd
get really bored if you had to do the same thing lots of times in a row. But a computer
can do the same thing millions or even billions of times and not get bored, and be able to
carry that out really well. For example, if I wanted to wish everyone on Facebook a Happy
Birthday by sending them an email, it might take me more than a century to actually write
out all of those emails to everyone. But with just a few lines of code I can have a system
send an email to everyone on Facebook wishing them a Happy Birthday. So that's what loops
are and why they're valuable, and something that computers can do very well. To get the
bird to the pig in this level... rather than drag three North blocks on to the workspace,
you will use the "repeat" block. Drag the "repeat" block on to the workspace and enter
the number 3. Then drag the "move North" block into the "repeat" block and hit "Run" to see
if you got it right. Congratulations, you got it!
