What is semantic versioning?

Q: What is semantic versioning?

Short answer: Semantic Versioning (semver) is a versioning system that uses the format: MAJOR.MINOR.PATCH Example: 2.5.3 MAJOR: Breaking changes MINOR: New features, no breaking changes PATCH: Bug fixes, backwards-compatible 📌 Example: If a package moves from 1.2.0 to 2.0.0, it likely has breaking changes. In package.json, you might see: "express": "^4.17.1" ^ means it can auto-update minor and patch versions, but not major ones. Real-world example (ShopNest) A ShopNest BFF in Node.js aggregates catalog and price APIs for the React storefront. Say this in the interview Define — one clear sentence (the short answer above). Example — relate it to a project like ShopNest or your real work. Trade-off — when you would not use it.
