Convert an ArrayBuffer to a Buffer

The Node.js Buffer API predates the introduction of ArrayBuffer into the JavaScript language. Bun implements both.

Convert an ArrayBuffer to a string

Bun implements the Web-standard TextDecoder class for converting between binary data types and strings.

A Blob can be constructed from an array of "chunks", where each chunk is a string, binary data structure, or another Blob .
