Info

This test attempts to establish which function that strips quotes around a word is the fastest.

Preparation code

 
<script>
  Benchmark.prototype.setup = function() {
    var myString = "'this is a test'",
        result = "",
        rx1 = /^'([^']+)'$/,
        rx2B = /^'/,
        rx2A = /'$/;
    
    function trimQuote1(str) {
      return str.replace(rx1, "$1");
    }
    
    function trimQuote2(str) {
      return str.replace(rx2B, '').replace(rx2A, '');
    }
    
    function trimQuote3(str) {
      if (!str.indexOf("'") && str.slice(-1) === "'") {
        return str.slice(1, -1);
      }
    }
    
    function trimQuote4(s) {
      var str = s.match(rx1);
      return str ? str[1] : '';
    }
  };
</script>
