is-data-view 
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
var isDataView = require('is-data-view');
var assert = require('assert');
assert.equal(false, isDataView(undefined));
assert.equal(false, isDataView(null));
assert.equal(false, isDataView(false));
assert.equal(false, isDataView(true));
assert.equal(false, isDataView([]));
assert.equal(false, isDataView({}));
assert.equal(false, isDataView(/a/g));
assert.equal(false, isDataView(new RegExp('a', 'g')));
assert.equal(false, isDataView(new Date()));
assert.equal(false, isDataView(42));
assert.equal(false, isDataView(NaN));
assert.equal(false, isDataView(Infinity));
assert.equal(false, isDataView(new Number(42)));
assert.equal(false, isDataView('foo'));
assert.equal(false, isDataView(Object('foo')));
assert.equal(false, isDataView(function () {}));
assert.equal(false, isDataView(function* () {}));
assert.equal(false, isDataView(x => x * x));
assert.equal(false, isDataView([]));
assert.equal(false, isDataView(new Int8Array()));
assert.equal(false, isDataView(new Uint8Array()));
assert.equal(false, isDataView(new Uint8ClampedArray()));
assert.equal(false, isDataView(new Int16Array()));
assert.equal(false, isDataView(new Uint16Array()));
assert.equal(false, isDataView(new Int32Array()));
assert.equal(false, isDataView(new Uint32Array()));
assert.equal(false, isDataView(new Float32Array()));
assert.equal(false, isDataView(new Float64Array()));
assert.equal(false, isDataView(new BigInt64Array()));
assert.equal(false, isDataView(new BigUint64Array()));
assert.ok(isDataView(new DataView(new ArrayBuffer(0))));
