+A this kulcsszó használatával a függvénykiterjesztésekben az objektum, amelyre alkalmazni szeretnénk a kiterjesztett metódust, paraméterként jut át a metódusnak.
+Ez a példa egy egyszerű függvénykiterjesztés az int típushoz, amely a szám faktoriálisát számítja ki.
+
+A throw kulcsszót a hiba vagy kivétel dobása céljából használhatunk.
+Amikor egy kivételt dobunk akkor valamilyen előre definiált kivételosztály egy példányát kaphatjuk vissza, vagy saját magunk által definiált kivételosztály.
+
+A throw tehát lehetővé teszi  számunkra, hogy megállítsuk a program futását és jelezzük, hogy valamilyen probléma vagy kivlételes helyzet áll fennm amely kezelést igényel.
