What Are Streams?
A stream is an abstract interface that lets you perform specific tasks continuously. A stream is an EventEmitter that implements different methods. A user can use streams to perform a variety of tasks, like read, write, and transform functions.
In a Node.js environment, streams are used to work with streaming data. It provides users with an API that helps them in creating the streaming interface. The data here is received in parts and is read in parts as well.
