TypeScript, when run in a Node.js environment, allows you to check if a directory exists by using the fs module, which provides the existsSync() function or the asynchronous access() function combined with constants.F_OK.

Creating a temporary file in TypeScript isn’t baked in, but you can use the fs module in Node.js to do the job.
Let’s read a text file in TypeScript using Node.js’s fs/promises module.

In TypeScript, you use Node.js to read command line arguments.
TypeScript itself doesn’t directly handle file operations as it compiles to JavaScript, which traditionally runs in the browser with limited access to the file system.
TypeScript, being a superset of JavaScript, relies on the underlying JS runtime environment (like Node.js) for writing to stderr.
