I am reading jshint source code and found return void error("E009"); line.

I know void means return nothing in languages such as C and C++. But what does it mean in javascript and how can it be used? Or is it good practice to use it in Javascript?

    Both the linked answers show usage in links, where you don't want the page to change. This usage is similar but different. Compared to "error(x); return void 0;" it saves on 1 line and the braces on the conditional. Compared to "return error(x);" it saves you having to read the code for error() and figuring out that it returns undefined - which, in fact, it does. Neither of these advantages add up to much, it just seems to be this coder's style (he calls the commit just a 'minor refactoring' https://github.com/jshint/jshint/commit/bb04a20796f50ba30498c947f4f9271a03362bde) – bazzargh Mar 24 '14 at 09:37
