regex exec 1

var regex = /[&?](?:_x_tr_tl=([\w-]+)|fb_locale=([\w-]+)|lang=([\w-]+)|hl=([\w-]+)|locale=([\w-]+)|_x_tr_hl=([\w-]+))/g;

replaceAll beforehand

var finalResult = Array.prototype.concat(resultList[0],resultList[1],resultList[2],resultList[3],resultList[4],resultList[5]);

several matches for loop

several matches concat

var result = Array.prototype.concat(

var result = Array.prototype.concat(
  standardQuery.match(/[&?]-x-tr-tl=([\w-]+)/g),

urlSearchParams

  searchParams.getAll('fb-locale'),
  searchParams.getAll('lang'),
