# Loops

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

> Rust has three kinds of loops: `loop`, `while`, and `for`. The `loop` keyword tells Rust to execute a block of code over and over again forever or until you explicitly tell it to stop. `while` loops evaluate a block of code until a condition ceases to be true. A `for` loop executes some code for each item in a collection.

    loop {
        println!("again!");
    }

    let mut number = 3;
    while number != 0 {
        println!("{number}!");
        number = number - 1;
    }

    let a = [10, 20, 30, 40, 50];
    for element in a.iter() {
        println!("the value is: {element}");
    }
