Select util function for redux - saves milliseconds in your typing :)

select.js

// @flow

export const select = (selectors: Object) => (state: Object): Object => {
  const keys = Object.keys(selectors);
  const ret = {};
  keys.forEach(key => {
    if (!selectors[key]){
      throw new Error(
        `
Could not find key '${key}' in selectors. 
Perhaps you the selector doesn't exist or is misspelt? 
Or maybe imported selector in component is misspelt?
`,
      );
    }
    ret[key] = selectors[key](state);
  });
  return ret;
};
