The Let-It-Crash Philosophy
Understand Erlang's let-it-crash mindset and how isolating errors, restarting cleanly, and avoiding defensive coding produce more reliable systems.
A Different Mindset
Most languages encourage catching every possible error. Erlang takes the opposite view: let it crash. A process that hits an unexpected state should die and be restarted into a known-good state.
Why Crashing Is Good
A crash is a clean, well-defined failure. Trying to limp along in a corrupted state often causes worse, harder-to-debug problems later.
