Setup

var testString = '///foo/is/not/equal/to/bar///';
  
  function normalize1(path) {
    return path.replace(/^\/+|\/+$/g, '');
  }
  
  function normalize2(path) {
    while (path.charAt(0) === '/') {
      path = path.slice(1)
    }
    while (path.slice(-1) === '/') {
      path = path.slice(0, -1)
    }
  }
  
  function normalize3(path) {
    var a = 0;
    var b = path.length - 1;
    while (path.charAt(a) === '/' && ++a);
    while (path.charAt(b) === '/' && --b);
    path = path.slice(a, b + 1);
  }
  
  function normalize4(path) {
    var a = 0;
    var b = path.length - 1;
    while (path.charCodeAt(a) === 47 && ++a);
    while (path.charCodeAt(b) === 47 && --b);
    path = path.slice(a, b + 1);
  }
