data-view-byte-length

Get the byteLength 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.byteLength has been deleted after this module has loaded.

Example

```js const dataViewByteLength = require('data-view-byte-length'); const assert = require('assert');

const ab = new ArrayBuffer(42); const dv = new DataView(ab); assert.equal(dataViewByteLength(dv), 42); ```

Tests

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