    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

    var isTypedArray = require('is-typed-array');
    var assert = require('assert');
    
    assert.equal(false, isTypedArray(undefined));
    assert.equal(false, isTypedArray(null));
    assert.equal(false, isTypedArray(false));
    assert.equal(false, isTypedArray(true));
    assert.equal(false, isTypedArray([]));
    assert.equal(false, isTypedArray({}));
    assert.equal(false, isTypedArray(/a/g));
    assert.equal(false, isTypedArray(new RegExp('a', 'g')));
    assert.equal(false, isTypedArray(new Date()));
    assert.equal(false, isTypedArray(42));
    assert.equal(false, isTypedArray(NaN));
    assert.equal(false, isTypedArray(Infinity));
    assert.equal(false, isTypedArray(new Number(42)));
    assert.equal(false, isTypedArray('foo'));
    assert.equal(false, isTypedArray(Object('foo')));
    assert.equal(false, isTypedArray(function () {}));
    assert.equal(false, isTypedArray(function* () {}));
    assert.equal(false, isTypedArray(x => x * x));
    assert.equal(false, isTypedArray([]));
    
    assert.ok(isTypedArray(new Int8Array()));
    assert.ok(isTypedArray(new Uint8Array()));
    assert.ok(isTypedArray(new Uint8ClampedArray()));
    assert.ok(isTypedArray(new Int16Array()));
    assert.ok(isTypedArray(new Uint16Array()));
    assert.ok(isTypedArray(new Int32Array()));
    assert.ok(isTypedArray(new Uint32Array()));
    assert.ok(isTypedArray(new Float32Array()));
    assert.ok(isTypedArray(new Float64Array()));
    assert.ok(isTypedArray(new BigInt64Array()));
    assert.ok(isTypedArray(new BigUint64Array()));
