Represents a raw buffer of binary data, which is used to store data for the different typed arrays. ArrayBuffers cannot be read from or written to directly, but can be passed to a typed array or DataView Object to interpret the raw buffer as needed.

readonly [Symbol.toStringTag]: stringreadonly byteLength: number

Read-only. The length of the ArrayBuffer (in bytes).

resize(newByteLength?: number): void;

Resizes the ArrayBuffer to the specified size (in bytes).

MDN

resize(byteLength: number): ArrayBuffer;

Resize an ArrayBuffer in-place.

slice(begin: number,end?: number): ArrayBuffer;

Returns a section of an ArrayBuffer.

transfer(newByteLength?: number): ArrayBuffer;

Creates a new ArrayBuffer with the same byte content as this buffer, then detaches this buffer.

MDN

transferToFixedLength(newByteLength?: number): ArrayBuffer;

Creates a new non-resizable ArrayBuffer with the same byte content as this buffer, then detaches this buffer.
