Determines if two array buffers contain the exact same content. Works in node 0.10+ and in the browser using browserify.
npm install --save arraybuffer-equal
var isEqual = require('arraybuffer-equal');
var buf1 = new Uint8Array([0x50, 0x0a]).buffer;
var buf2 = new Uint8Array([0x50, 0x0a]).buffer;
var buf3 = new Uint8Array([0x50, 0x0b]).buffer;
var buf4 = new Uint8Array([0x50, 0x0b, 0x15]).buffer;
assert(isEqual(buf1, buf1));
assert(isEqual(buf1, buf2));
assert(!isEqual(buf1, buf3));
