RegExp test vs looping indexOf

Benchmark created by grammarxcore on

Setup

var notAcceptedArray = ['<', '>', '[', ']', '(', ')', ',', ';', '/', '\\', '\'', '"'];
  
  function checkAgainstNotAcceptedArray(str) {
      for (var i = 0; i < notAcceptedArray.length; i++) {
          if (str.indexOf(notAcceptedArray[i]) > -1)
              return false;
      };
  
      return true;
  };
  
  var notAcceptedRegExp = /[<>\(\)\[\],;\\\/'"]/;
  
  function checkAgainstNotAcceptedRegExp(str) {
      return notAcceptedRegExp.test(str);
  }
  
  var acceptedRegExp = /^[\w\- ]+$/;
  
  function checkAgainstAcceptedRegExp(str) {
      return acceptedRegExp.test(str);
  }
