JavaScript Design Patterns
summary
Shows idiomatic JavaScript design patterns and concrete implementations: an Option/Setup pattern that merges defaults using Object.assign or jQuery.extend and TypeScript for compile-time checks; a small delegate utility using Element.matches for event delegation (demo toggles a class); replacing long switch statements with a lookup map (Map or plain object); and a factory-as-map that returns constructors by key. Also lists required browser APIs and polyfills and points out where boilerplate or copy‑paste code can be eliminated.
