Question 1

What is the role of React and Next.js in this stack, and how do they relate to each other?

Accepted Answer

React is the library for building user interfaces out of individual, reusable components written in JavaScript. Next.js by Vercel is a full-stack React framework that builds on top of React, adding server-side rendering and static site generation to help developers create fast, user-friendly web applications.

Question 2

Why is TypeScript included in this stack instead of plain JavaScript?

Accepted Answer

TypeScript extends JavaScript by adding types to the language. It speeds up the development experience by catching errors and providing fixes before you even run your code, which is especially valuable in production-ready applications where type safety matters.

Question 3

What is the difference between TanStack Query and Zustand, and when would you use each?

Accepted Answer

TanStack Query is focused on asynchronous state management and data fetching. It handles fetching, caching, and updating server-state without touching global state. Zustand, on the other hand, is a small, fast, and scalable state management solution for React applications, designed for managing local or client-side application state with ease and efficiency.

Question 4

How does Zod complement TypeScript in this stack?

Accepted Answer

Zod is a TypeScript-first schema validation library that offers static type inference. While TypeScript provides compile-time type checking, Zod allows developers to define and validate data structures at runtime, ensuring type safety in applications when dealing with external or dynamic data.

Question 5

What is Tailwind CSS and how does it differ from traditional CSS approaches?

Accepted Answer

Tailwind CSS is a utility-first CSS framework for rapidly building modern websites without ever leaving your HTML. Rather than writing custom CSS in separate files, developers apply pre-built utility classes directly in their markup, which speeds up the styling process significantly.
