I believe a streaming API would be more appropriate for such a task.
Something like:
var deleter = new Deleter('~');
deleter.on('error', function (err) {
console.error(err)
})
deleter.on('file', function (fileName) {
console.log('deleted ' + fileName)
})
deleter.on('end', function () {
console.log('done!');
})

Let's say that somewhere within your library, you delete the contents of a
directory in parallel. Let's say all the files in a directory are read-only so
all your parallel requests return an error.
If you've exposed a Node.js style asynchronous function with an `(error, result,
result...)` callback, how do you report multiple errors to person who called
your library? Do you wrap the multiple errors in a single error, maybe having an
array of `causes`? Do you note that multiple errors may be returned?
Are the functions in the Node.js API that might return more than one error that
I could study? Do any of the event emitters in the Node.js API emit a series of
errors, or is it just one error prior to entering an error state?
