Personally I don't like using with prefix in builders, I was simply presenting an example from another comment.

the difference, IMO, is - in Javascript - that this

    // The style fetch() uses today
    trig({mode: "cos", typ: "hyperbolic"})
                       ^^^

would fail silently while

    // The builder refactor
    trig().mode("cos").typ("hyperbolic")(val)

would trigger a compilation error

but, IMO, passing objects is good enough most of the times, and I consider it a much better solution over passing boolean flags
