Working with Writable Streams in Node.js

0.0% Acceptance

In this lab, you will create a WritableStream which reads data from a file and converts it to uppercase using the stream.WritableStream.from() method in Node.js. You will then save the processed data to a new file. The stream.WritableStream.from() method is a utility to create writable streams.

This lab will enhance your understanding of working with writable streams and provide practical experience in implementing them in a Node.js application.
