  iterator,
  "url_new_win",
  "link_open",
  function(tokens, idx) {
    var aIndex = tokens[idx].attrIndex("target");

    if (aIndex < 0) {
      tokens[idx].attrPush(["target", "_blank"]);
    } else {
      tokens[idx].attrs[aIndex][1] = "_blank";
    }
  }
);

const text = "http://www.baidu.com";
var result = md.render(text);
console.log(result);
