Fixing TypeScript's Blindspot: Runtime Typechecking

TypeScript only checks types at compile time. And that means that, invalid data, that doesn't have the fields we think are required, can still break our applications. Learn how to use Zod, Yup, and Joi to fix this problem and go even further to check the contents of the fields at runtime.

Yup: https://github.com/jquense/yup
Joi: https://joi.dev/api/?v=17.4.2
