These are concise but detailed notes on NPM, ideal for quick reference or documentation.

🔢 Semantic Versioning

Semantic Versioning helps manage your code versions with meaning, Semantic means the numbers mean something.

• Format: Major.Minor.Patch (e.g., 1.7.2)
  • Patch: Bug fixes (e.g., 1.7.2 → 1.7.3)
  • Minor: New small features that don’t break the existing code (e.g., 1.7.2 → 1.8.0)
  • Major: Significant changes that may break backward compatibility (e.g., 1.7.2 → 2.0.0)

📌 Version Prefixes

Example:

"moment": "^2.30.1"

• ^ (Caret): Automatically update to minor and patch versions.
• ~ (Tilde): Only update patch versions.

📦 Dependencies vs DevDependencies

• Dependencies: Required for the app to run in production.
• DevDependencies: Only needed during the development phase.

🚀 NPM Install Commands
