节点：从声明模块中调用导出的函数

Question

I need to export a recursive function. Is it okay to refer to the exports object from within a function? (I'm worried about the circular reference).

exports.traverse = function(node, cb){
  if(node.hasOwnProperty("value")){
    cb(node.value);
  }else if(node.hasOwnProperty("children")){
    node.children.forEach(function(child){
      exports.traverse(child, cb);  // Err, is this ok ?
    });
  }
}

It is OK, it works, but there's a cleaner solution:

exports.traverse = function traverse(node, cb){
  if(node.hasOwnProperty("value")){
    cb(node.value);
  }else if(node.hasOwnProperty("children")){
    node.children.forEach(function(child){
      traverse(child, cb);
    });
  }
}
