Variables & Constants | IOS Development | Tarang Sultania

Ever wondered why some values in code change while others stay fixed forever? That’s where var and let come in.

✅ Variable (var) → Values you can update anytime (like your game score).
✅ Constant (let) → Values that never change (like your birth year).

Rule of thumb: Use let by default and var only when necessary. This simple habit keeps your code clean, safe, and bug-free.
