Rust: println!()

    println!("{greeting}, {name}!"); // Hello, world!

    println!("{:?}", [1, 2, 3]); // [1, 2, 3]

    // 🔎 The format! macro is used to store the formatted string.
    let x = format!("{}, {}!", "Hello", "world");
    println!("{}", x); // Hello, world!

    // 💡 Rust has a print!() macro as well
    print!("Hello, world!"); // Without new line
    println!(); // A new line

    print!("Hello, world!\n"); // With new line
