There are a lot of sources discussing the void operator in JavaScript and I'm sure we've all seen it. It comes in handy in Bookmarklets, in href URLS (though it's not recommended to do that), and for ensuring that you're returning undefined and not a shadowed version of undefined.
But there's another interesting use pointed out on MDN and in a comment on an article on void (see references below). It looks like this:
|
void function() {
// function body here...
}();
|
(JS Bin) MDN explains: "When using an immediately-invoked function expression, void can be used to force the function keyword to be treated as an expression instead of a declaration."
From what I understand, this is basically an alternative to the usual IIFE methods, but with arguably a simpler syntax potentially making it easier to read and understand what's happening at a glance. But interestingly, in JavaScript: The Good Parts, Douglas Crockford says void in JavaScript is confusing and not consistent with how void is used in other languages, so he recommends to avoid it (no pun intended).
Nonetheless, good to know what it does and how it can be used, so check out the resources below for more:
