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. So for example, if I wanted to wish everyone on Facebook a happy birthday

by sending them an email, it might take me more than century to actually write out all

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 are valuable and something that computers can do very well.

In this example, your goal is going to be to move the bird to get the pig. Now, we're going to be able

to use the repeat block in order to be able to do this very easily. You can either do

this by giving the computer a move forward command five times in order to advance the

bird one step each time to the pig or you can just tell the computer to move forward

once, and then tell it to repeat that five times and it'll do the same thing. So in order

to do this, you drag your move forward command and then you put it inside the repeat block.

And you can click on it and tell it how many times you want to repeat the block to tell it how

many steps you want it to take forward. Now one more thing is you can put as many commands

as you want inside the repeat block. So in this example, you're telling it to move forward

and turn left, which it'll do five times. All right, good job and have fun!
