|
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`
