Why use parentheses when returning in JavaScript?

Question

In the Restify framework code I found this function:

function queryParser(options) {

    function parseQueryString(req, res, next) {
        // Some code goes there
        return (next());
    }
    return (parseQueryString);
}

Why would the author write return (next()); and return (parseQueryString);? Does it need parentheses there and if so, why?

Answer 1

It doesn't need to be that way, but it's valid JavaScript code. Actually it's quite uncommon to see such syntax. I guess it's a personal preference of the author.
