There is something really nice. You can use the ... operator when calling a
function. For example, if you're wrapping a function foo:
_origFoo = foo;
foo = function (a, b, ...rest) {
// ... do something ...
return _origFoo(a, b, ...rest);
};
If you're wrapping a method it's not quite as nice, but:
_origMethod = Bar.prototype.method;
Bar.prototype.method = function (a, b, ...rest) {
// ... do something ...
return _origMethod.call(this, a, b, ...rest);
};
-j
