Node.js API Masterclass with Express and MongoDB - Advanced Results Middleware

The video tutorial explains how to refactor code by creating a middleware function for advanced results in a Node.js application. This middleware is designed to handle filtering, pagination, and selection for various resources like boot camps and courses. The tutorial covers the creation of the middleware, its integration into routes, and testing its functionality using Postman. The goal is to make the code more modular and reusable across different resources.
