 * STRICTLY `fn.apply(y, arguments)` is ok, nothing else is (e.g. `.slice`). That's because `Function#apply` is special.
 * Be aware that adding properties to functions (e.g. `fn.$inject =...`) and bound functions (i.e. the result of `Function#bind`) generate hidden classes and, therefore, are not safe when using `.apply`.
 
-If you need to manipulate `arguments`, use a copy. [sliced](https://github.com/aheckmann/sliced) is a good tiny library for this purpose.
+If you need to process the input of a function as an `array`, a good perfomance approach is manipulate a copy of `arguments`. You can do it using `spread operator`:
+
+```js
+function spreadOp(...args) {
+  return other(args)
+}
+```
+
+If you are in a scenario where is not possible to use `spread operator`, we recommend use the tiny [sliced](https://github.com/aheckmann/sliced) library for make an a copy of the `array`:
+
+```js
+const sliced = require('sliced');
+
+function myFunctionWithArgs() {
+  const args = sliced(arguments)
+}
+```
