reactjs - How would I call a selector within another selector and pass on the Redux state?

Let's say I have a selector like this:

const selectItemByGuid = (state, guid) => {
    return state.items.find(i => i.guid == guid)
}

Now, I want to apply that selector to each guid in a list of guids.

export const selectSpecialItems = createSelector(
    [selectSpecialEntityGuids],
    guids => {
        const items = guids.map(guid => selectItemByGuid(state, guid)) // Where do I get state here?
        return items || []       
    },
)

How would I pass in state to the inner selector?

You can pass state to your selectSpecialItems function as such which can then pass it down as an argument:

 export const selectSpecialItems = createSelector(
    [selectSpecialEntityGuids, state => state],
    (guids, state) => {
    ...
