The Power of Early Returns

Deeply nested "if" statements are a common source of bugs and cognitive load. A great way to clean up your logic is by using the "Early Return" pattern. Instead of wrapping your entire function logic inside a giant conditional block, check for edge cases or invalid states at the very top and return immediately.

This flattens your code and makes the "happy path" much easier to follow. When you see a function that stays at one indentation level for the most part, it’s usually a sign of a well-thought-out, readable design that’s easy to maintain long-term.
