| 10 | An ES spec-compliant `ArrayBuffer.prototype.slice` shim. Invoke its "shim" method to shim ArrayBuffer.prototype.slice if it is unavailable.
|
|---|
| 11 |
|
|---|
| 12 | This package implements the [es-shim API](https://github.com/es-shims/api) interface. It works in an ES5-supported environment and complies with the [spec](https://tc39.es/ecma262/#sec-arraybuffer.prototype.slice).
|

| 13 |
|
|---|
| 14 | Most common usage:
|
|---|
| 15 | ```js
|
|---|
| 16 | var assert = require('assert');
|
|---|
| 17 | var slice = require('arraybuffer.prototype.slice');
|
|---|
| 18 |
|
|---|
| 19 | var ab = new ArrayBuffer(1);
|
|---|
| 20 | var arr = new Uint8Array(ab);
|
|---|
| 21 | arr[0] = 123;
|
|---|
| 22 |
|
|---|
| 23 | var ab2 = slice(ab);
|
|---|
| 24 |
|
|---|
| 25 | var arr2 = new Uint8Array(ab2);
|
|---|
| 26 | arr2[0] = 234;
|
|---|
| 27 |
|
|---|
| 28 | assert.deepEqual(arr, new Uint8Array([123]));
|
|---|
| 29 | assert.deepEqual(arr2, new Uint8Array([234]));
|
|---|
| 30 |
|
|---|
| 31 | if (!ArrayBuffer.prototype.transfer) {
|
|---|
| 32 | slice.shim();
|
|---|
| 33 | }
|
|---|
| 34 |
|
|---|
| 35 | var ab2 = ab.slice();
|
|---|
| 36 |
|
|---|
| 37 | var arr2 = new Uint8Array(ab2);
|
|---|
| 38 | arr2[0] = 234;
|
|---|
| 39 |
|
|---|
| 40 | assert.deepEqual(arr, new Uint8Array([123]));
|
|---|
| 41 | assert.deepEqual(arr2, new Uint8Array([234]));
|
