Rust 101 - What are scopes

Wow, we made it to a very serious topic today. It might not seem like it, but scopes are one of the essential concepts that you have to understand fully if you wish to ever become a great developer, no matter if you are learning Rust or any other programming language out there. But if you wish to learn Rust, scopes have even deeper meaning than in many other languages, so you better pay close attention to this lesson and get as much as possible out of it! I hope you will enjoy the lesson!
