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;

  });

  return pen;

};

I meant clicking on the grey checkmark next to the answer in such a way it becomes green :) It means that « you received an answer that worked for you personally », see stackoverflow.com/help/accepted-answer. In addition it kind of rewards the person who answered correctly by giving him some more reputation.
