๐ Topic Summary
Abstraction is like simplifying complex things! In computer science, it means hiding the details and showing only what's important. Think of a car ๐ โ you only need to know how to drive it, not how the engine works internally. In Scratch, abstraction can involve using custom blocks to represent a whole series of commands.
