  > A list of helpful front-end related questions you can use to interview potential candidates, test yourself or completely ignore.
- [The Twelve-Factor App](https://12factor.net/)
  > The twelve-factor app is a methodology for building software-as-a-service apps that:
  >
  > - Use **declarative** formats for setup automation, to minimize time and cost for new developers joining the project;
  > - Have a **clean contract** with the underlying operating system, offering **maximum portability** between execution environments;
  > - Are suitable for **deployment** on modern **cloud platforms**, obviating the need for servers and systems administration;
  > - **Minimize divergence** between development and production, enabling **continuous deployment** for maximum agility;
  > - And can **scale up** without significant changes to tooling, architecture, or development practices.
