Not sure why author uses the phrase "pattern matching algorithm". There is nothing algorithmical about it. This is just a pattern matching language feature similiar to Haskell's. And since JS is dynmatically typed, I believe this is really just sytnax sugar at the interpreter level. Unless there is something time/space-specific about it, invoking "algorithm" feels to me an abuse of terminology. Of course will love to be enlightened otherwise.
