This hardly covers any functional patterns that javascript is capable of. You can compose functions, avoid stack overflows in tail call recursion, use immutable values, etc. I've seen articles on pattern matching with Typescript or trampolining code but this is simple a descriptive look at three basic javascript functions. If you're interested in more of a functional approach in JS take a look at Immutable.js and/or https://pattern-matching-with-typescript.alabor.me/ https://pattern-matching-with-typescript.alabor.me/.
