Mo' Problems, Mo 'Nads
summary
Covers how concrete monad values solve three common problems with runnable examples: Maybe (Just/Nothing) for value selection shows replacing null checks and nested ternaries with maybe.from, map and fold (regex mime parsing example); Either (Left/Right) for graceful errors shows a safe helper that wraps parse/save into chained either values instead of nested try/catch; IO with .run plus do/generator syntax wraps lazy side effects and promises (playlist concat, yield weight → IO of a promise) using the moneo library.
