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

| 11 |
|

| 12 | ## Example
|
|---|
| 13 |
|
|---|
| 14 | ```js
|
|---|
| 15 | var isDataView = require('is-data-view');
|
|---|
| 16 | var assert = require('assert');
|
|---|
| 17 |
|
|---|
| 18 | assert.equal(false, isDataView(undefined));
|
|---|
| 19 | assert.equal(false, isDataView(null));
|
|---|
| 20 | assert.equal(false, isDataView(false));
|
|---|
| 21 | assert.equal(false, isDataView(true));
|
|---|
| 22 | assert.equal(false, isDataView([]));
|
|---|
| 23 | assert.equal(false, isDataView({}));
|
|---|
| 24 | assert.equal(false, isDataView(/a/g));
|
|---|
| 25 | assert.equal(false, isDataView(new RegExp('a', 'g')));
|
|---|
| 26 | assert.equal(false, isDataView(new Date()));
|
|---|
| 27 | assert.equal(false, isDataView(42));
|
|---|
| 28 | assert.equal(false, isDataView(NaN));
|
|---|
| 29 | assert.equal(false, isDataView(Infinity));
|
|---|
| 30 | assert.equal(false, isDataView(new Number(42)));
|
|---|
| 31 | assert.equal(false, isDataView('foo'));
|
|---|
| 32 | assert.equal(false, isDataView(Object('foo')));
|
|---|
| 33 | assert.equal(false, isDataView(function () {}));
|
|---|
| 34 | assert.equal(false, isDataView(function* () {}));
|
|---|
| 35 | assert.equal(false, isDataView(x => x * x));
|
|---|
| 36 | assert.equal(false, isDataView([]));
|
|---|
| 37 | assert.equal(false, isDataView(new Int8Array()));
|
|---|
| 38 | assert.equal(false, isDataView(new Uint8Array()));
|
|---|
| 39 | assert.equal(false, isDataView(new Uint8ClampedArray()));
|
|---|
| 40 | assert.equal(false, isDataView(new Int16Array()));
|
|---|
| 41 | assert.equal(false, isDataView(new Uint16Array()));
|
|---|
| 42 | assert.equal(false, isDataView(new Int32Array()));
|
|---|
| 43 | assert.equal(false, isDataView(new Uint32Array()));
|
|---|
| 44 | assert.equal(false, isDataView(new Float32Array()));
|
|---|
| 45 | assert.equal(false, isDataView(new Float64Array()));
|
|---|
| 46 | assert.equal(false, isDataView(new BigInt64Array()));
|
|---|
| 47 | assert.equal(false, isDataView(new BigUint64Array()));
|
|---|
| 48 |
|
|---|
| 49 | assert.ok(isDataView(new DataView(new ArrayBuffer(0))));
|
|---|
| 50 | ```
