ArrayBuffer

ArrayBuffer is a low-level JavaScript object used to represent a fixed-length raw binary data buffer. It provides a way to handle binary data directly in memory, enabling efficient manipulation of data such as images, audio, or network packets. It serves as the foundation for typed array views like Int8Array or Float64Array, which allow structured access to the buffer's contents.

Also known as: Array Buffer, ArrayBuffer object, Binary buffer, Raw buffer, AB

🧊Why learn ArrayBuffer?

Developers should learn ArrayBuffer when working with binary data formats, Web APIs like WebGL, Web Audio, or File API, or when implementing performance-critical operations that require direct memory access. It is essential for tasks such as processing image data, handling network protocols, or interfacing with hardware where raw byte manipulation is necessary.
