      const subtotalSelector = createSelector( shopItemsSelector, items => items.reduce((acc, item) => acc + item.value, 0) )

      This is a memoized selector. items.reduce will be evaluated during the first call. Any subsequent call with the same parameters will return the result without computing items.reduce.
