| 10 | Is this value a JS ArrayBuffer? This module works cross-realm/iframe, does not depend on `instanceof` or mutable properties, and despite ES6 Symbol.toStringTag.

| 12 | ## Example
|
|---|
| 13 |
|
|---|
| 14 | ```js
|
|---|
| 15 | var assert = require('assert');
|
|---|
| 16 | var isArrayBuffer = require('is-array-buffer');
|
|---|
| 17 |
|
|---|
| 18 | assert(!isArrayBuffer(function () {}));
|
|---|
| 19 | assert(!isArrayBuffer(null));
|
|---|
| 20 | assert(!isArrayBuffer(function* () { yield 42; return Infinity; });
|
|---|
| 21 | assert(!isArrayBuffer(Symbol('foo')));
|
|---|
| 22 | assert(!isArrayBuffer(1n));
|
|---|
| 23 | assert(!isArrayBuffer(Object(1n)));
|
|---|
| 24 |
|
|---|
| 25 | assert(!isArrayBuffer(new Set()));
|
|---|
| 26 | assert(!isArrayBuffer(new WeakSet()));
|
|---|
| 27 | assert(!isArrayBuffer(new Map()));
|
|---|
| 28 | assert(!isArrayBuffer(new WeakMap()));
|
|---|
| 29 | assert(!isArrayBuffer(new WeakRef({})));
|
|---|
| 30 | assert(!isArrayBuffer(new FinalizationRegistry(() => {})));
|
|---|
| 31 | assert(!isArrayBuffer(new SharedArrayBuffer()));
|
|---|
| 32 |
|
|---|
| 33 | assert(isArrayBuffer(new ArrayBuffer()));
|
|---|
| 34 |
|
|---|
| 35 | class MyArrayBuffer extends ArrayBuffer {}
|
