Early Return
ELI5 — The Vibe Check
Early return is exiting a function as soon as you have the answer, instead of setting a variable and waiting until the end. Some old-school devs insist functions should have exactly one return statement. Modern devs say 'return early, return often.' It makes code shorter, clearer, and avoids the 'what happens in the else branch?' mystery.
Real Talk
Early return is a coding pattern where a function returns as soon as a result is determined, rather than using a single exit point. It reduces nesting, improves readability, and pairs naturally with guard clauses. While the single-return convention originated from C's manual resource cleanup needs, modern languages with automatic resource management (RAII, finally, defer) make early returns safe and preferred.
When You'll Hear This
"Use early return — don't make me scroll to find the else branch." / "Early returns eliminated half the nesting in this function."
