Do I need to `return` after `throw` in JavaScript?

I'm throwing an Error from a method of mine that I want an early exit from, as below:

// No route found
if(null === nextRoute) {
    throw new Error('BAD_ROUTE');
}

Do I need to put a return; statement after my throw? It works for me, for now. If it's superfluous I'd rather not put it in, but I can't be sure what different browsers might do.

Solution 1:

You do not need to put a return statement after throw, the return line will never be reached as throwing an exception immediately hands control back to the caller.

Solution 2:

The throw statement throws a user-defined exception. Execution of the current function will stop (the statements after throw won't be executed), and control will be passed to the first catch block in the call stack. If no catch block exists among caller functions, the program will terminate.
