Buffers (1/6)
What are buffers?
    It is a built-in object in Node.js that represents binary data.
    • It is useful when working with binary streams or when interfacing with non-JavaScript systems or protocols.
    • Buffer objects are used to represent a fixed-length sequence of bytes. Many Node.js APIs support Buffers.
    • The Buffer class is a subclass of JavaScript's Uint8Array class, extending it with methods that cover additional use cases.
    • While the Buffer class is available within the global scope, it is still recommended to reference it via an import or require statement explicitly.
    • They are used to create multiple chunks of data for processing instead of all of it immediately.
    • It is used in storing streaming data before processing.
