reducer.js

function wrap_selectors (selectors, state_path) {
  const wrapped_selectors = {}

  Object.keys(selectors).forEach(selector_key => {
    wrappedSelectors[selectorKey] = (state, ...args) => selectors[selectorKey](state[statePath], ...args)
  })

  return wrapped_selectors
}

export const selectors = {
  ...wrap_selectors(shared_datetime_selectors, "shared_datetime"),
