Forward-like but for list of pairs of units

[sergeysova]

Now

forward({
  from: navigation.historyPush,
  to: app.navigation.historyPush,
});
forward({
  from: navigation.historyPushSearch,
  to: app.navigation.historyPushSearch,
});
forward({
  from: navigation.historyReplace,
  to: app.navigation.historyReplace,
});

Proposal

forwardPairs([
  [navigation.historyPush, app.navigation.historyPush],
  [navigation.historyPushSearch, app.navigation.historyPushSearch],
  [navigation.historyReplace, app.navigation.historyReplace],
])

I like the idea, but this name sounds weird to me.
Maybe something like forwardMap would fit better?

I think that forwardMany is a good option - it's clear and short.

forwardMap has some collisions with the functions like useStoreMap, where the word map is used for describing "mapping". Though this function has something like "mapping", I don't think this is the same as in the other functions.

Also, maybe some additional enchanced api would make sense?

Like this:

forwardPairs({
  base, // Record<string, Unit>
  target, // Record<string, Unit>
  rule, // (basePropName: string): string => targetPropName
})

// and then just
forwardPairs({
  base: navigation,
  target: app.navigation,
  rule: (name) => name, // makes more sense as a default option with api like that
})

Looks like the edge-case =)

Yeah, it's good for @sergeysova example, but imagine the usage without "scopes" with units.

I was thinking that this operator should support both options - if there are "scopes" and it is possible to have some "rule" to map them to each other - then this api would help
For all other cases there would be the first api with explicit relations
