Return void(0); vs return; interrupting functions [duplicate]

Question

I ran across some code that interrupts a function return void(0);.

I believe that is being used to return undefined but that can be done simply by writing return;.

Does return void(0); serve an additional purpose, or is this just two different ways to interrupt a function?

Answer 1

return void(0); doesn't do anything special. It simply returns undefined, albeit in a very silly way. It's probably a case of the original developer not understanding JavaScript fully.

Answer 2

It's just another way to return undefined. See https://developer.mozilla.org/en-US/docs/JavaScript/Reference/Operators/void
