# `const` and `static`

There is a new edition of the book and this is an old link.

> 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.

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