- Which kind of Typed Array is this JavaScript value? Works cross-realm, without `instanceof`, and despite Symbol.toStringTag.
- ## Example
- ```js
- var whichTypedArray = require('which-typed-array');
- var assert = require('assert');
- assert.equal(false, whichTypedArray(undefined));
- assert.equal(false, whichTypedArray(null));
- assert.equal(false, whichTypedArray(false));
- assert.equal(false, whichTypedArray(true));
- assert.equal(false, whichTypedArray([]));
- assert.equal(false, whichTypedArray({}));
- assert.equal(false, whichTypedArray(/a/g));
- assert.equal(false, whichTypedArray(new RegExp('a', 'g')));
- assert.equal(false, whichTypedArray(new Date()));
- assert.equal(false, whichTypedArray(42));
- assert.equal(false, whichTypedArray(NaN));
- assert.equal(false, whichTypedArray(Infinity));
- assert.equal(false, whichTypedArray(new Number(42)));
- assert.equal(false, whichTypedArray('foo'));
- assert.equal(false, whichTypedArray(Object('foo')));
- assert.equal(false, whichTypedArray(function () {}));
- assert.equal(false, whichTypedArray(function* () {}));
- assert.equal(false, whichTypedArray(x => x * x));
- assert.equal(false, whichTypedArray([]));
- assert.equal('Int8Array', whichTypedArray(new Int8Array()));
- assert.equal('Uint8Array', whichTypedArray(new Uint8Array()));
- assert.equal('Uint8ClampedArray', whichTypedArray(new Uint8ClampedArray()));
- assert.equal('Int16Array', whichTypedArray(new Int16Array()));
- assert.equal('Uint16Array', whichTypedArray(new Uint16Array()));
- assert.equal('Int32Array', whichTypedArray(new Int32Array()));
- assert.equal('Uint32Array', whichTypedArray(new Uint32Array()));
- assert.equal('Float32Array', whichTypedArray(new Float32Array()));
- assert.equal('Float64Array', whichTypedArray(new Float64Array()));
- assert.equal('BigInt64Array', whichTypedArray(new BigInt64Array()));
- assert.equal('BigUint64Array', whichTypedArray(new BigUint64Array()));
- ```
