In C++

Vector elbow = hand.arm().elbowPosition();
Vector wrist = hand.arm().wristPosition();

maybe the JS correspondents are not that different.

when i gave similar code in JavaScript it gave results as undefined

   var elbow = frame.hands[0].arm.elbowPosition;
console.log("elbow :"+elbow);
var wrist = frame.hands[0].arm.wristPosition;
console.log("wrist :"+wrist);

-----results ----------------------------
frame id : 50189
elbow :undefined
wrist :undefined

What will be the issue ?

Sorry for the stupid question, didi you try to use them? not just to print them.
In C++ you get nothing by printing a Vector, you have to call the toString() method in order to get a printable representation of its three values - maybe you experienced something like that.
Yet, if you already tried to use them unsuccessfully the problem is elsewhere.
