What is Semantic Versioning?

Semantic versioning (SemVer) is a three-part numbering system: MAJOR.MINOR.PATCH. Each number tells you exactly what changed and whether it'll break your code.

The Format Breakdown

• MAJOR - Incompatible changes that will break existing code
• MINOR - New features that won't break anything
• PATCH - Bug fixes only

Example: Version 2.1.3 means 2 major breaking changes, 1 new feature added, and 3 bug fixes since the last minor release.

Why Use It?

• Instant clarity - Anyone can tell the impact of an update at a glance
• Safe updates - Know if upgrading will break your project
• Team communication - Universal language for discussing changes

Implementation with Git Tags

• Commit your changes: git commit -m "Add user authentication"
• Tag the version: git tag -a v1.2.0 -m "Add authentication feature"
• Push tags: git push origin main --tags

Quick npm Automation

For npm projects, automate the whole process:

npm version minor - Updates package.json and creates a Git tag automatically

Regarding your portfolio question:

This is actually perfect for a portfolio. Here's why:

1. It's fundamental knowledge that many developers don't fully grasp
2. Shows you understand professional workflows - versioning is crucial in real development
3. Demonstrates clear communication skills - explaining technical concepts simply is valuable
4. It's practical - employers want developers who understand release management

Far from looking junior, this shows you understand the bigger picture of software development beyond just writing code. Keep it!
