Modern JavaScript from the Beginning - Second Edition - fs (filesystem) Module

This video tutorial covers the use of the Node.js FS module for file system operations. It explains how to write files using asynchronous callbacks, promises, and synchronous methods. The tutorial also demonstrates reading, deleting, and renaming files, as well as creating directories. The instructor provides code examples and discusses error handling techniques. The video concludes with a brief mention of the FS module's documentation for further exploration.
