what is checkout-validation fr?

This project is a working demo of a checkout form, the kind you'd fill out when buying something online. Instead of being a real store, it's a practice project that shows how to build a checkout page and validate what customers enter. The app uses Angular, a popular JavaScript framework for building interactive web applications. It also uses a validation library that checks whether the information customers type in is correct and complete before they can submit their order. For example, it might verify that an email address looks like a real email, that a zip code has the right format, or that required fields aren't left blank. The main value here is as a learning tool or reference. If you're building an e-commerce site and want to see a working example of how to create a checkout form with built-in validation, this gives you something concrete to study or adapt. You can try it live online to see how it behaves, filling in fields, watching error messages appear if you enter invalid data, and submitting when everything checks out. The README doesn't explain many implementation details, but the core idea is straightforward: it's a single-page application, meaning everything happens in your browser without constant page reloads. When you interact with the form, JavaScript running on the page instantly validates your input and gives you feedback, making the experience smooth and responsive.
