Node.js Buffer
Node.js Buffer is a built-in global object that provides a way to handle binary data directly in memory, representing a fixed-size chunk of raw bytes. It is essential for working with file systems, network streams, and other I/O operations where data is not in text format. Buffers are particularly useful for performance-critical applications that process large amounts of binary data efficiently.
Developers should learn Node.js Buffer when building applications that involve binary data manipulation, such as image processing, video streaming, or network protocols like TCP/UDP. It is crucial for handling raw data from files, databases, or external APIs where encoding and decoding are required, ensuring efficient memory usage and avoiding string conversion overhead in Node.js environments.
