Redeclare immutable variable - Shadowing

---

• You can actually change even an immutable variable by declaring it again.
• It can be useful if you need to make a few changes and then later no more changes.

examples/variables/shadow/src/main.rs

fn main() {
    let name = "Foo";
    println!("{name}");

    let name = "Bar";
    println!("{name}");
}

Foo
Bar
