The role of spacing in code readability? Let me tell you a secret - I once saw code without spaces. It looked like someone dropped their keyboard down the stairs and just published whatever came out.

Think of code spacing like social distancing for functions. Without it, all your variables start getting too friendly with each other and next thing you know, your code's throwing a party you didn't authorize.

Seriously though, proper spacing is like giving your code a nice suit. Makes it look professional, even if it's just printing 'Hello World' for the 100th time.
