What is the difference between static and dynamic typing?

Short answer: Static typing: Variable types are known at compile-time (e.g., TypeScript, Java). Dynamic typing: Types are determined at runtime (JavaScript). Example: let x = 10; // number

Example code

x = "text"; // allowed

Say this in the interview

1. Define — one clear sentence (the short answer above).
2. Example — relate it to a project like ShopNest or your real work.
3. Trade-off — when you would not use it.
