Looking for best practice to use createSelector

[ethan-cao]

Hi,

I was wondering what's the best practice to handle the following case

const selector1 = (state, key, type) => { 
  if  (type === 1) {
     return state.list1.filter(entry => entry.key === key)
  } else {
     return state.list2.filter(entry => entry.key === key)
  }
}

const selector2 = (state) => state.a.b.key

const selector3 = (state) => state.c.d.type

const selector4 = createSelector(
  selector2,
  selector3,
  (key, type) => {
     // how can I use selector1 here? 
     // basically, I wanna use key and type as cache keys to skip calling selector1 if they remain the same as previous call
     // what would be the best way to do it?
  }
)

Many thanks.
