为什么JSON.stringify()不显示prop2？

var newObj = {
  prop1: true,
  prop2: function(){
    return "hello";
  },
  prop3: false
};

alert( JSON.stringify( newObj ) ); // prop2 appears to be missing

alert( newObj.prop2() ); // prop2 returns "hello"

for (var member in newObj) {
    alert( member + "=" + newObj[member] ); // shows prop1, prop2, prop3
}
