// It's possible to do this in one line if you would like!
// Some similar examples from other languages:
// - In C(++) this would be: `a > b ? a : b`
// - In Python this would be: `a if a > b else b`
// Remember in Rust that:
// - the `if` condition does not need to be surrounded by parentheses
// - `if`/`else` conditionals are expressions
// - Each condition is followed by a `{}` block.
