Buffer is a built-in global class used to handle raw binary data. Buffers represent raw binary data allocated outside the V8 heap in Node.js. Buffers are regions of memory used to hold data temporarily while it is being transferred from one place to another. They are used to improve the efficiency of data transfer by allowing devices to operate at different speeds. Buffers can be used in a variety of contexts, including input/output operations, network communication, and data processing. They help to prevent data loss and corruption by providing a temporary storage area for data that is being transferred.
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.
