An easier alternative is to wrap the value into an array, then use `.map()` for each function in the chain, and finally escape the value with `[0]`

I made a similar data structure[1] to allow adding side effect (no return value) as part of the chained function.

If you extract this `Chain` class to a separate package, I would gladly reuse it in my applications. I've been thinking about creating a `Vavr`[0] clone in typescript, as I really like the syntax used in that library, especially the `Try` construct.

This works great for small datasets, but often you’ll have to eventually use streams rather than arrays. I’ve used pull-stream to do this in the past.

.use is a nice quality of life feature!
