The Streams are the objects that facilitate you to read data from a source and write data to a destination. There are four types of streams in Node.js:

• Readable: This stream is used for reading operations.
• Writable: This stream is used for write operations.
• Duplex: This stream can be used for both reading and write operations.
• Transform: It is a type of duplex stream where the output computes according to input.
