Understanding Deno’s file system

Deno offers a versatile file system module that allows for various file and directory manipulations, though some methods remain experimental and require the --unstable flag. Key functionalities include writing and reading files using methods like Deno.writeTextFile, Deno.writeFile, and Deno.readTextFile, as well as removing files with remove and removeSync. The system also supports checking and ensuring the existence of directories and files through methods like ensureDir and ensureFile, copying file contents with the copy method, and emptying directories using emptyDir. A notable feature is Deno's ability to create a simple CLI application that utilizes command-line arguments to create files. When working with Deno's file system, users should be aware of the distinct use cases for synchronous and asynchronous methods and consider chunked writing for larger files.
