    //=> <Buffer 01 02 03 04>
     
    const arr = new Uint8Array([1, 2, 3, 4])
    console.log(bufferFrom(arr.buffer, 1, 2))
    //=> <Buffer 02 03>
     
    console.log(bufferFrom('test', 'utf8'))
    //=> <Buffer 74 65 73 74>

    API

    bufferFrom(array)

    • array <Array>

    Allocates a new Buffer using an array of octets.

    bufferFrom(arrayBuffer[, byteOffset[, length]])

    • 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.

    bufferFrom(buffer)

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

    Copies the passed buffer data onto a new Buffer instance.

    bufferFrom(string[, encoding])

    • 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.
