createStructuredSelector is a convenience function for a common pattern that arises when using Reselect. The selector passed to a connect decorator often just takes the values of its input-selectors and maps them to keys in an object:

createStructuredSelector takes an object whose properties are input-selectors and returns a structured selector. The structured selector returns an object with the same keys as the inputSelectors argument, but with the selectors replaced with their values.

export function createStructuredSelector(selectors, selectorCreator = createSelector) {
  if (typeof selectors !== 'object') {
    throw new Error(
      'createStructuredSelector expects first argument to be an object ' +
      `where each property is a selector, instead received a ${typeof selectors}`
    )
  }
  const objectKeys = Object.keys(selectors)
  return selectorCreator(
    objectKeys.map(key => selectors[key]),
    (...values) => {
      return values.reduce((composition, value, index) => {
        composition[objectKeys[index]] = value
        return composition
      }, {})
    }
  )
}
