<script>
  var strings = [];
  for (var i = 0; i < 500; ++i) {
   strings[i] = "The end of the beginning? Or the beginning of the end?";
  }
  
  var regexString1 = "beginning",
      regexString2 = "(end of).*(end)",
      regexString3 = "beginnizg";

  var regex1 = new RegExp(regexString1),
      regex2 = new RegExp(regexString2),
      regex3 = new RegExp(regexString3);
