+Agar siz ushbu kodni kompilyatsiya qilishga harakat qilsangiz, quyidagi xatolik kelib chiqadi:

-However, there are situations in which it would be useful for a value to mutate
-itself in its methods but appear immutable to other code. Code outside the
-value’s methods would not be able to mutate the value. Using `RefCell<T>` is
-one way to get the ability to have interior mutability, but `RefCell<T>`
-doesn’t get around the borrowing rules completely: the borrow checker in the
-compiler allows this interior mutability, and the borrowing rules are checked
-at runtime instead. If you violate the rules, you’ll get a `panic!` instead of
-a compiler error.

-Let’s work through a practical example where we can use `RefCell<T>` to mutate
-an immutable value and see why that is useful.
+Shunday vaziyatlar borki qiymat o'zini-o'zi o'zining metodlarida o'zgarivchan qilishi
+foydali hisoblanadi, lekin boshqa kodda o'zgarmas shaklda bo'ladi. Kodning doirasidan
+tashqaridagi qiymat metodi qiymatni o'zgaruvchan qila olmaydi. `RefCell<T>`ni ishlatish ichki
+o'zgaruvchanlikga ega bo'lishning bir yo'li hisoblanadi, lekin `RefCell<T>` borrowing 
+qoidalarini to'liq aylanib o'tmaydi: kompilyatorda borrow tekshiruvchisi shu ichki o'zgaruvchanlikka
+ruxsat beradi, va borrowing qoidalari runtimes tekshiriladi. Agar qoidalarni rad etsangiz,
+kompilyator xatoligini o'rniga `panic!` ko'rasiz.
