var ddoc = {
      _id: '_design/following',
      views: {
        [req.body.userName]: {
          map: function (doc) {
            for (var key in req.body.following) {
              eval(' if (' + req.body.following[key].userName + ' === req.body.userName) { ' +
                'emit(doc.dateApproved);' +
                '} ')
            }
          }
        }
      }
    } ```


I would like the output to look like this..

 var ddoc = {
  _id: '_design/index',
  views: {
    TerryFollower: {
      map: function(doc) {
        if (doc._id === "JohnFollowing") {
          emit(doc.dateApproved);
        }
        if (doc._id === "TimFollowing") {
          emit(doc.dateApproved);
        }
        if (doc._id === "DaveFollowing") {
          emit(doc.dateApproved);
        }

      }.toString()
    }
  }
}
