Add `mapAccum` about remeda

[cjquines]

you might be looking for https://remedajs.com/docs/#mapWithFeedback

(it's not quite that, but it can be easily built from that)

I'm looking for something like that, yes. Specifically I am looking for a function like mapWithFeedback/mapAccum, but for values in a Record<T, U>.

[cjquines]

can you give an example of what that'd look like? i'm not sure what you mean here; mapAccum doesn't do that either

[ludwignagelhus]

In Haskell I think there is a implementation for this, but not 100% sure.

const result = mapAccumObj({a: 1, b: 2, c: 4 }, (acc, n) => acc + inc(n), 0); // { a: 2, b: 5, c: 10 }

Similar to mapValues, but for mapAccum.

i'm not sure i see the use of this... entries in an object don't have an order they appear in. (technically, the order they're enumerated is consistent, but i don't think that records should be treated as having an order; in that case you want an array)
