I've always wondered how this was done. Now I know.

Security is a top priority for web applications, as they can be vulnerable to various threats. This is where Server Actions come in. They include features like encrypted closures, strict input checks, error message hashing, host restrictions, and more — all working together to significantly enhance your application security.

Covering:

• What React Server Actions are and how to use them to mutate data.
• How to work with forms and Server Components.
• Best practices for working with the native FormData object, including type validation.
• How to revalidate the client cache using the revalidatePath API.
• How to create dynamic route segments with specific IDs.

Loving the inspect and play with the PR before more functionality. That has to be a winner anywhere. If this was actual functionality, I'd suggest form validation, but I can see that comes in the next chapter of the course.
