API

$3

- array <Array>

Allocates a new Buffer using an array of octets.

$3

- arrayBuffer <ArrayBuffer> The .buffer property of a TypedArray or ArrayBuffer
- byteOffset <Integer> Where to start copying from arrayBuffer. Default: 0
- length <Integer> How many bytes to copy from arrayBuffer. Default: arrayBuffer.length - byteOffset

When passed a reference to the .buffer property of a TypedArray instance, the
newly created Buffer will share the same allocated memory as the TypedArray.

The optional byteOffset and length arguments specify a memory range within
the arrayBuffer that will be shared by the Buffer.

$3

- buffer <Buffer> An existing Buffer to copy data from

Copies the passed buffer data onto a new Buffer instance.

$3

- string <String> A string to encode.
- encoding <String> The encoding of string. Default: 'utf8'

Creates a new Buffer containing the given JavaScript string string. If
provided, the encoding parameter identifies the character encoding of
string.
