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.

Example

1var isDataView = require('@asdfgertyjhnpm/illum-eius-odio');
2var assert = require('assert');
3
4assert.equal(false, isDataView(undefined));
5assert.equal(false, isDataView(null));
6assert.equal(false, isDataView(false));
7assert.equal(false, isDataView(true));
8assert.equal(false, isDataView([]));
9assert.equal(false, isDataView({}));
10assert.equal(false, isDataView(/a/g));
11assert.equal(false, isDataView(new RegExp('a', 'g')));
12assert.equal(false, isDataView(new Date()));
13assert.equal(false, isDataView(42));
14assert.equal(false, isDataView(NaN));
15assert.equal(false, isDataView(Infinity));
16assert.equal(false, isDataView(new Number(42)));
17assert.equal(false, isDataView('foo'));
18assert.equal(false, isDataView(Object('foo')));
19assert.equal(false, isDataView(function () {}));
20assert.equal(false, isDataView(function* () {}));
21assert.equal(false, isDataView(x => x * x));
22assert.equal(false, isDataView([]));
23assert.equal(false, isDataView(new Int8Array()));
24assert.equal(false, isDataView(new Uint8Array()));
25assert.equal(false, isDataView(new Uint8ClampedArray()));
26assert.equal(false, isDataView(new Int16Array()));
27assert.equal(false, isDataView(new Uint16Array()));
28assert.equal(false, isDataView(new Int32Array()));
