func1() calls func2() twice. func2() calls func3() a variable number of times (based on a parameter that is passed to it). As node.js is asynchronous, how can I tell when the last call to func3() has finished executing? Assume I do not know how many times func3() would be called.
This ought to be simple but is definitely out of my reach.
Thanks
Without async you may simply writes console.log('yep') or many others at end of code-block of func3(). If you want - write there you code for details of help.
