| 10 | Get the `byteOffset` out of a DataView, robustly.
|
|---|
| 11 |
|
|---|
| 12 | This will work in node <= 0.10 and < 0.11.4, where there's no prototype accessor, only a nonconfigurable own property.
|
|---|
| 13 | It will also work in modern engines where `DataView.prototype.byteOffset` has been deleted after this module has loaded.
|
|---|
| 14 |
|
|---|
| 15 | ## Example
|
|---|
| 16 |
|
|---|
| 17 | ```js
|
|---|
| 18 | const dataViewByteOffset = require('data-view-byte-offset');
|
|---|
| 19 | const assert = require('assert');
|
|---|
| 20 |
|
|---|
| 21 | const ab = new ArrayBuffer(42);
|
|---|
| 22 | const dv = new DataView(ab, 2);
|
|---|
| 23 | assert.equal(dataViewByteOffset(dv), 2);
|
|---|
| 24 | ```
|
|---|
| 25 |
|
|---|
| 26 | ## Tests
|
|---|
| 27 | Simply clone the repo, `npm install`, and run `npm test`
