Chapter 36 — Browser Storage (localStorage, sessionStorage, cookies): Exercise 3 — Hard

Exercise 3 — Hard

Task:
Oddiy "Eslatmalar" (Notes) funksiyasini yozing: addNote(text) — yangi eslatmani localStoragedagi array'ga qo'shadi (avval mavjud eslatmalarni JSON.parse bilan o'qib, yangisini qo'shib, qayta JSON.stringify bilan saqlaydi). getNotes() — barcha eslatmalarni array sifatida qaytaradi.
Required Concepts:

• localStorage + JSON
• Array metodlari (Chapter 7)
  Hint:
  Agar localStorageda hali eslatmalar bo'lmasa, getItem() — null qaytaradi, shuni tekshirib, bo'sh array bilan boshlang.
