Buffer.buffer

Example

In this example will create a buffer and see the output for NodeJS Buffer.buffer.

const buf = Buffer.from('Hello World');
console.log(buf.buffer);

Output

ArrayBuffer {
  [Uint8Contents]: <63 6f 6e 73 74 20 62 75 66 20 3d 20 42 75 66 66 65 72 2e 66 72 6f 6d 28 27 
48 65 6c 6c 6f 20 57 6f 72 6c 64 27 29 3b 0d 0a 0d 0a 63 6f 6e 73 6f 6c 65 2e 6c 6f 67 28 62 75 66 2e 62 75 66 66 65 72 29 3b 0d 0a 02 00 00 48 65 6c 6c 6f 20 57 6f 72 6c 64 45 48 02 00 00 08 00 00 00 01 00 00 00 08 07 00 00 ... 8092 more bytes>,
  byteLength: 8192 }

Example

In this example let us create an array buffer and later a buffer from it. And compare both.

const arrofbuff = new ArrayBuffer(16);
const buff = Buffer.from(arrofbuff);
if (buff.buffer === arrofbuff) {
   console.log("Buffer and array buffer are equivalent");
}

Output

Buffer and array buffer are equivalent
