js字符串处理之绝妙的代码

function uniqStr(str) {
  var str = str.split('');
  var zarr = [];
  for (var i = 0; i < str.length; i++) {
    if (zarr.indexOf(str[i]) === -1) {
      zarr.push(str[i])
    }
  }
  return str.join('')
}

    r: "s",
    o: "i",
    t: "c",
    n: "u",
    F: "a"
  };
  var g = Object.keys(obj).concat(Object.values(obj));
  var str = str.split('/');
  var sr = '';
  for (var i = 0; i < str.length; i++) {
    sr = sr + g[str[i]];
  }
  return sr;
}
sc("4/8/3/7/2/6/1/3");//"constructor"
