Complete Git Guide: Understand and Master Git and GitHub - Adding Multi and Sum Modules with Tests

The video tutorial covers the basics of Node.js modules, explaining how to manage dependencies using NPM. It guides viewers through creating simple JavaScript modules for sum and multiplication functions, and demonstrates how to export these modules. The tutorial then shifts to testing, showing how to write and execute tests using Jest. Finally, it discusses automating test execution with pre-commit hooks in Git, ensuring tests run before each commit.
