Getting Started with Rust as a JavaScript Developer

Rust might seem intimidating, but JavaScript developers have a great foundation for learning it.

Memory Management

The biggest difference is memory management. Rust uses ownership and borrowing.

fn main() {
    let s1 = String::from("hello");
    let s2 = s1; // s1 is now invalid (moved)
    // println!("{}", s1); // This would fail!
    println!("{}", s2);
}

Pattern Matching

Rust's pattern matching is powerful and expressive:

match value {
    1 => println!("one"),
    2 | 3 => println!("two or three"),
    4..=10 => println!("four to ten"),
    _ => println!("something else"),
}

Conclusion

Rust is challenging but rewarding. Start with the basics and practice consistently!
