Node.js - Using the async lib - async.foreach with object

The final function does not get called because async.forEach requires that you call the callback function for every element.

Use something like this:

async.forEach(Object.keys(dataObj), function (item, callback){     console.log(item); // print the key    // tell async that that particular element of the iterator is done    callback(); }, function(err) {    console.log('iterating done');});  

async.each is very useful and powerful function which is provided by Async Lib .it have 3 fields1-collection/array2- iteration3-callbackthe collection is referred to the array or collection of objects and iteration is refer to the each iteration and callback is optional .if we are giving callback then it will return the response or say result which you want to show you in the frontend

Applies the function iteratee to each item in coll, in parallel. The iteratee is called with an item from the list, and a callback for when it has finished. If the iteratee passes an error to its callback, the main callback (for the each function) is immediately called with the error.

Note, that since this function applies iteratee to each item in parallel, there is no guarantee that the iteratee functions will complete in order.

exapmle-

 var updateEventCredit = function ( userId, amount ,callback) {    async.each(userId, function(id, next) {    var incentiveData = new domain.incentive({    user_id:userId,        userName: id.userName,        amount: id.totalJeeneePrice,        description: id.description,    schemeType:id.schemeType    });    incentiveData.save(function (err, result) {        if (err) {            next(err);        } else {                 domain.Events.findOneAndUpdate({                    user_id: id.ids                }, {                    $inc: {                        eventsCredit: id.totalJeeneePrice                    }                },{new:true}, function (err, result) {                    if (err) {                        Logger.info("Update status", err)                        next(err);                    } else {                     Logger.info("Update status", result)                     sendContributionNotification(id.ids,id.totalJeeneePrice);                     next(null,null);                           }                });        }    });
