[[A scope block is an expression]]
[[Loop labels]]


A loop can return values, it is an expression. Thus it can be used in an assignment as well.
It is possible to `return ` but that would exit the function, instead we can also `break expression;` and return a value just from the loop by breaking it with a value (as we would normally write a `return`).

```rust
fn main() {
    let mut counter = 0;

    let result = loop {
        counter += 1;

        if counter == 10 {
            break counter * 2;
        }
    };

    println!("The result is {result}");
}
```
