22. What is JAMstack and what are its advantages?

JAMstack is a modern web development architecture based on three main components: JavaScript, APIs, and Markup. JAMstack allows for creating fast, secure, and scalable websites.

Advantages of JAMstack:

1. Performance: Static sites can be served from a CDN, ensuring fast load times.
2. Security: No application server means a smaller attack surface.
3. Scalability: Static files can be easily scaled globally using a CDN.
4. Better development: Decoupling layers allows for independent development of frontend and backend.
5. Lower costs: Fewer server resources mean lower operational costs.
