Place Query Search Parameters Into a Hash

An ES6-friendly means to place all query string arguments into a hash with key mapped to value. (URLSearchParams doesn't seem to be especially good for this.) Note, the use of spread operator here will reduce any duplicate keys to the final item iterated through.

export const locationSearchToHash = paramsString => {
  return paramsString.slice(1).split('&').reduce((acc, current) => {
    let pair = current.split('=');
    if (pair.length === 2) {
      let ins = {};
      ins[pair[0]] = pair[1];
      return { ...acc, ...ins };
    } else {
      return acc;
    }
  }, {});
};
