1 year ago Rust doesn't actually require a mut modifier or a type annotation. You can see for yourself in the playground: https://play.rust-lang.org/?version=stable&mode=debug&edition=2021&gist=c4a0e8058e9417f0469b71c2afef4b65

The first question in the first quiz of the Control Flow page does not compile, since the variable is not mutable and there is no type annotation or value to infer the type. I added mutability to the variable and defined it to 0.
