I would like to add logging to a composed chain of functions like so
const f = R.compose(
transformation2,
doAlso(x => console.log(`id: ${x.id}`)),
transformation1
)
Which would first apply transformation1 and then log the id of the resulting value before passing it to transformation2.
It would be quite easy to implement
doAlso = f => x => {
f(x)
return x
}
But it seems like it should be a quite common pattern. Is this concept called something? Does a similar function exist in FP libs like ramda?
