🧠 Interface vs Type in 2025: Which to Use and When?

Still debating interface vs type?
✅ Use interface when:
– You describe objects
– You want better compile time
– You need declaration merging
✅ Use type when:
– You define unions, tuples, or mapped structures
– You need flexibility and composability
🧩 My rule: Start with interface; switch to type when shapes get advanced.
