📚 Topic Summary
Imagine you're building with LEGOs. You wouldn't just randomly stack bricks, right? You'd plan it out! Code comments are like those planning notes for your code. They're explanations you write within your code that the computer ignores, but humans use to understand what's going on. Think of them as breadcrumbs that guide you or another programmer through the logic of your program. They clarify what a specific piece of code does, why it was written that way, and sometimes even how it interacts with other parts of the program.
Unplugged activities like this one help you grasp the concept of code comments without even needing a computer. You'll understand how crucial they are for collaboration, debugging, and simply remembering what your code does months or years later! 👍
