Have you ever heard of debugging a program?
This is the way you figure out what's not

2
00:00:10,010 --> 00:00:17,140
working. When you debug code, you identify
and remove errors. Here we're given a few

00:00:17,140 --> 00:00:22,170
blocks already in our workplace. We're going
to use the step button to walk through the

4
00:00:22,170 --> 00:00:27,920
blocks, step by step, to see if this is the
right solution and where we may need to fix

5
00:00:27,920 --> 00:00:34,650
it. Looks like there's our problem! We need
one more move forward block. The step button

6
00:00:34,650 --> 00:00:44,140
helps us debug our problem by identifying
where the error is so we can fix it.
