Frequently Asked Questions

What is a GitHub Actions matrix strategy?

A matrix strategy allows a single job definition to run multiple jobs concurrently by substituting combinations of variables (such as OS runners and programming language versions).

Can I use this for Python or Go test matrices?

Yes! While the template defaults to Node.js, the resulting table and YAML structure can easily be tailored for Python (e.g. `python-version: ['3.10', '3.11', '3.12']`) or Go runners.
