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

asynchronous, loops, node-async, node.js, object

Solution

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');
});

Problem

I am using the node async lib - https://github.com/caolan/async#forEach and would like to iterate through an object and print out its index key. Once complete I would like execute a callback. Here is what I have so far but the `'iterating done'` is never seen: ``` async.forEach(Object.keys(dataObj), function (err, callback){ console.log('*****'); }, function() { console.log('iterating done'); }); ``` Why does the final function not get called? How can I print the object index key?
