Building a ChatGPT AI with JavaScript - An OpenAI Code-Along Guide - Overview of Next.js Key Index and Starter Coding Fi

The video tutorial covers error handling in a development server, focusing on a missing CSS file. It explains the roles of key application files like index.js and app.js, introduces higher order components in React, and discusses how Next.js renders HTML. The tutorial also includes a cleanup of unused styles and files, concluding with a summary and future goals for integrating AI into the app.

What is the primary role of the index.js file in a Next.js application?

• To handle API requests and responses
