data-view-byte-offset

Get the byteOffset out of a DataView, robustly.

This will work in node <= 0.10 and < 0.11.4, where there's no prototype accessor, only a nonconfigurable own property. It will also work in modern engines where DataView.prototype.byteOffset has been deleted after this module has loaded.

Example

const dataViewByteOffset = require('data-view-byte-offset'); const assert = require('assert');

const ab = new ArrayBuffer(42); const dv = new DataView(ab, 2); assert.equal(dataViewByteOffset(dv), 2);

Tests

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