Custom HTTP Library (Fetch with Promises) - Part 3

This video tutorial covers the modernization of HTTP requests using JavaScript. It introduces the use of fetch, ES6 classes, and promises to handle GET, POST, PUT, and DELETE requests. The tutorial demonstrates how to implement these requests in a cleaner and more efficient way compared to older methods. It concludes with a brief introduction to async/await, setting the stage for further exploration in the next video.
