You are confusing "chaining" with "composition". The two have fundamental differences. This confusion is understandable though because languages without a strong type system make true composition very loose (the exception being stack based languages, I think).

Javascript is a poor language for composition; stream programming is uniquely suited to strongly typed languages with denotational semantics that make function composition natural and you'll probably be seeing much more of Elm and other Haskell to Javascript compilers taking the stage for this.
