In Swift, you can use underscores as thousand separators in numeric literals to make them more readable. It's like giving your numbers a quick makeover for clarity! This feature is not just a pretty face; it helps prevent silly mistakes when dealing with large numbers. No more misplaced zeros leading you astray!
// km to the moon
let distanceToMoon = 384_400_000

let pi = 3.141_592_653_589
/// Binary, but fashionable
let binaryExample = 0b0010_1010
