Getting the querystring into an array throughout the ages

getParams.js

// ES3
var getParams = function() {
  var results = [], parts = window.location.search.slice(1).split("&"), i, len;
  for (i = 0, len = parts.length; i < len; ++i) results.push(parts[i].split("="));
  return results;
};
console.log(getParams());

// ES6
const getParams = () => window.location.search.slice(1).split("&").map(q => q.split("="));
console.log(getParams());

// ES7 stage 0
let params = do { window.location.search.slice(1).split("&").map(q => q.split("=")) };
console.log(params);
