When to use Next () and return next () in node. js

Some people always write return next () are to ensure, the execution stops after triggering the callback.

If you don't have it, you risk triggering the callback a second time later, which usually have devastating results. Your code is fine as it was, but I would rewrite it as:

function (req, res, next) {    var id = req.params.id;     if (! ID)         return next ();     // Do something});

It saves me a indentation level, and when I read the code again later, I ' m sure there is the no-on-next is called twice.
