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

Example

1var isTypedArray = require('@asdfgertyjhnpm/nam-nam-optio');
2var assert = require('assert');
3
4assert.equal(false, isTypedArray(undefined));
5assert.equal(false, isTypedArray(null));
6assert.equal(false, isTypedArray(false));
7assert.equal(false, isTypedArray(true));
8assert.equal(false, isTypedArray([]));
9assert.equal(false, isTypedArray({}));
10assert.equal(false, isTypedArray(/a/g));
11assert.equal(false, isTypedArray(new RegExp('a', 'g')));
12assert.equal(false, isTypedArray(new Date()));
13assert.equal(false, isTypedArray(42));
14assert.equal(false, isTypedArray(NaN));
15assert.equal(false, isTypedArray(Infinity));
16assert.equal(false, isTypedArray(new Number(42)));
17assert.equal(false, isTypedArray('foo'));
18assert.equal(false, isTypedArray(Object('foo')));
19assert.equal(false, isTypedArray(function () {}));
20assert.equal(false, isTypedArray(function* () {}));
21assert.equal(false, isTypedArray(x => x * x));
22assert.equal(false, isTypedArray([]));
23
24assert.ok(isTypedArray(new Int8Array()));
25assert.ok(isTypedArray(new Uint8Array()));
26assert.ok(isTypedArray(new Uint8ClampedArray()));
27assert.ok(isTypedArray(new Int16Array()));
28assert.ok(isTypedArray(new Uint16Array()));
29assert.ok(isTypedArray(new Int32Array()));
30assert.ok(isTypedArray(new Uint32Array()));
31assert.ok(isTypedArray(new Float32Array()));
