What are some examples of streams in Node.js?

Node.js streams are objects that allow you to read data from a source or write data to a destination in a continuous manner. Examples include readable streams like fs.createReadStream() for reading files, and writable streams like fs.createWriteStream() for writing files.

Can you explain how to use a readable stream?

Sure! To use a readable stream, you can create one using fs.createReadStream(), then listen for the 'data' event to read chunks of data as they become available.

What about writable streams? How do they work?

Writable streams allow you to write data to a destination. You can create one using fs.createWriteStream(), and then use the write() method to send data to it.

Are there any examples of transforming streams?

Yes! You can use the stream.Transform class to create a transforming stream. For example, you can create a stream that converts all input data to uppercase.
