在javascript/node.js中有没有等同于python的inspect.getargspec？

function greet(name, age) {
  console.log("Hello, " + name + "! You are " + age + " years old.");
}

function getArgs(func) {
  var str = func.toString();
  var args = str.match(/function\s.*?\(([^)]*)\)/)[1];
  return args.split(',').map(function(arg) {
    return arg.trim();
  });
}

function greet(name, age) {
  console.log("Hello, " + name + "! You are " + age + " years old.");
}

var args = getArgs(greet);
console.log(args);  // ["name", "age"]
