What is semantic versioning?

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.
