Basic Usage
var done = waitress(count, cb);
Waitress returns a function, done
, that will wait to be called count
times before executing the cb
passed into it.
var done = waitress(3, function(err) {
if (err) throw err;
});
done();
done(new Error('oh noes'));
done(false);
Getting results
If done receives a second parameter, waitress will add that to an array,
which will be the second parameter given to the callback, as long as it
receives no errors.
The array will be built in the order the data is received, not the order
done appears in your code.
var done = waitress(3, function(err, result) {
if (err) throw err;
result === ['a', 'b', 'c'];
});
done(null, 'a');
done(null, 'b');
done(null, 'c');
