Is it possible to finish async.js loop early?

Question

I am looking for a way to finish async.js loop early before all the callbacks get called. Is there any built-in function to do so? If not, is there any way around to achieve the desired functionality?

async.forEachOf(children, function(child, i, cb){

    if (condition == true) {

        // finish early - call cb() for all iterations

    }

    cb()

}, function(err){


})

You can make an async JS for loop yourself if you want the functionality, do you need a fiddle example on how to? — Dellirium, Jul 19 '16 at 09:51
It would be much appreciated if you help me with a fiddle example. — sawa, Jul 19 '16 at 10:14

Yes it is possible, you should pass a error parameter into your callback function like this:

async.forEachOf(children, function(child, i, cb){
    ....
    cb(condition)
}, function(err){
   // Error handling
})

If condition is True the loop will stop.
