1. A bug is just a mistake
When you write code, it's easy to make a mistake. Coding mistakes are called bugs.
Imagine you have written some code to make a game. You want your robot to move forwards when you press the arrow key, but the robot goes backwards!
When your code goes wrong, you need to check your algorithm and then check your code. When you have found and fixed your mistakes you can try the game again.
3. Problem or challenge?
What do you think about bugs? Are they an annoying problem or a helpful challenge? Choose from two options.
