node.js - How to change the order of the fields in JSON -


scenario: consider have json documents follows:

   {      "name": "david",      "age" : 78,      "noofvisits" : 4    }

issues: wanted change sequence/order of fields in document, want age, noofvisits & lastly name.

as of storing value in temporary variable, deleting field & recreating same field. since reassignment did not work :(

i did in following way: 

    temp = doc["age"];     delete doc['age'];     doc["age"] = temp;      temp = doc["noofvisits "];     delete doc['noofvisits '];     doc["noofvisits"] = temp;      temp = doc["name"];     delete doc['name'];     doc["name"] = temp;

so desired ordered json document. requirement peculiar kind still want efficient solution

question: can out efficient way achieve same?

may change using json.stringify()

do like

var json = {     "name": "david",     "age" : 78,     "noofvisits" : 4   }; console.log(json); //outputs - object {name: "david", age: 78, noofvisits: 4} //change order noofvisits,age,name  var k = json.parse(json.stringify( json, ["noofvisits","age","name"] , 4)); console.log(k); //outputs - object {noofvisits: 4, age: 78, name: "david"}

put key order want in array , supply function. parse result json. here sample fiddle.
