| > Constants are _always_ immutable, and may only be set to a constant expression, not the result of a function call or any other value that could only be computed at runtime. |
| > |
| > Global variables are called `static` in Rust. |

| ```rust |
| const MAX_POINTS: u32 = 100_000; |
| static HELLO_WORLD: &str = "Hello, world!"; |
