I needed this small function for one of my project.

[Fetch Attributes](http://jsbin.com/yuyajidaja/1/edit?html,js,console,output)

    function fetchAttrs(node) {
      
      if (!node || !node.hasAttributes()) return {};
      var attrs = node.attributes;
      var res = {};
      var length = attrs.length;
      for (var i = 0; i < length; i++) {
        var attr = attrs[i];
        res[attr.name] = attr.value;
      }
      return res;
    }

It's working fine as expected but I wanted to know if I am missing something from a performance point of view or good coding practices. Just need a second opinion :)
