some corrections
// parse location.search
if(!window.location.query) {
window.location.query = function(){
var map = {};

if ("" != this.search) {
  var groups = this.search.substr(1).split("&"), i=0, gL = groups.length;

  for ( ; i<gL; i++) {
	
    i = groups[i].split("=");
    map[decodeURIComponent(i[0])] = decodeURIComponent(i[1]);
  }
}

return map;

};
}

//some more corrections. Thanks for idea!

if ( !window.location.query ) {
window.location.query = () => Object.fromEntries(window.location.search.substr(1).split("&").map( group => group.split("=")));
}

Love the idea of using Object.fromEntries here is my take hope it helps someone.

function parseSearch (str = "") {
  const pairs = str
  	.replace(/^\?/, "")
  	.split("&")
  	.filter(Boolean)
  	.map((pair) => {
      const [key, value = ""] = pair.split("=")

      return [
        key,
        value.includes(",")
          ? value.split(",").map((v) => v.trim())
          : value
			]
    })
  
  return Object.fromEntries(pairs)
}
