For a functional programming analogy, JS promises are more like monads than about lazy evaluations. I don't know if there is a good Scheme analogy because in Scheme you can use call/cc and friends while in JS you are forced to write your async code in explicit continuation passing style (promises are just a way to make this a bit more manageable).
