This extension can be used to provide server-side and client-side form validation by executing the same JavaScript code at both places.

You can use function variables (jay!)

So the following works:

$add = function ($a, $b) {
return $a + $b;
};
$v8 = new V8Js('PHP', array('add' => 'add'));
$result = $v8->executeString('PHP.add(1,2)');
var_dump($result);

yields indeed:
int(3)

v8js can be also used to render server-side javascript components (see: React.js).
