array-buffer-byte-length

Get the byte length of an ArrayBuffer, even in engines without a .byteLength method.

Example

const assert = require('assert');
const byteLength = require('array-buffer-byte-length');

assert.equal(byteLength([]), NaN, 'an array is not an ArrayBuffer, yields NaN');

assert.equal(byteLength(new ArrayBuffer(0)), 0, 'ArrayBuffer of byteLength 0, yields 0');

Tests

Simply clone the repo, npm install, and run npm test
