Record and replay debugging is like playing a video game of your computer program. When you record your program, you keep track of every step it takes and what it's doing at each one of those steps. Just like in a video game, you can play back what you recorded to see what your program did every step of the way.
When you're replaying your program, you can pause and rewind it whenever you want to see what happened at a certain point. This helps you figure out what went wrong and how to fix it. It's like being able to go back in time in your video game to redo a level you messed up.
This is super useful when you're trying to figure out what caused a bug in your program because you can see exactly what was happening before it broke. Then, you can make changes to your code and replay it again to see if it worked and solved the problem.
