Abortable stream.Writable Lab

In this lab, you will work with Node.js stream.Writable module to create an abortable writable stream. The main objective is to create a custom writable stream that allows you to abort an ongoing write operation gracefully.

You will implement the following methods:

1. _write(chunk, encoding, callback): This is the main method responsible for writing the data.
2. abort(): This method will be used to abort the write operation.

Note: You need to export both AbortableWritableStream class and the instance abortableStream you create from it.

Prerequisites:

• Basic understanding of Node.js streams
• Familiarity with the concept of aborting in async processes
