'Why use return for methods that do not need a return value？

When I read the source code, I found that the author will use return where there is no need to use return.


exports.getPort = function (options, callback) {
    // code...
    return _async.eachSeries(exports._defaultHosts, function(host, next) {
        // code ...
        return next();
    }
}

What is the purpose or need of this usage?

javascript node.js

next is likely a promise. Maybe in your code it is not used (no then / catch), but there might (and should) be some.

In case the promise was not returned then there is no way to catch errors or make sequentials asynchronous calls.
