update function should accept just new data

[ayhanyunt12]

As per the documentation current update method accepts a callback function, we have some cases where we get the latest version of data entirely from the backend and we write logics like
promise(body).then(res => update(() => res))

Maybe changing update method can accept both of them?
update(currentData => ({ ...currentData, username: newUsername, })
update(latestData)

And usage would be more flexible.
promise(body).then(update)

It is possible to make it point-free by a few ramda helpers;

.then(converge(update, [always(res)])) // or
.then(chain(update, always(res)))

Not ideal, and I agree, accepting the final data from the original update API is a reasonable request.
