Mongo Async Driver: How to invoke a method after completion for foreach method

Question

I am writing a program for data migration. I want to invoke a method after complete execution of foreach method. In below code foreach(migrateJobsBlock, callback) callback method is invoked for every iteration. Is there any way I can invoke a method only after completion of foreach execution.

col1.find(filter).forEach(migrateBlock, callback).

Answer 1

Try something like:

var myCursor = db.doc.find( { filter } );

while (myCursor.hasNext()) {
   //do something
   var obj = myCursor.next()
}
// finished running! can run completion method
