          The following will do the job:



          exports.finalPen = functions.database
          
  .ref('/Sample/Pen/{penId}')
          
  .onCreate((snap, context) => {
          
    const createdData = snap.val(); // data that was created
          

          
    return admin
          
      .database()
          
      .ref('Final/Pen/' + snap.key)
          
      .set(setAllToZero(createdData));
          
  });
          

          
const setAllToZero = function(pen) {
          
  Object.keys(pen).forEach(function(key) {
          
    pen[key] = 0;
          
  });
