A gist that shows that no method of object type detection is infallible in ECMAScript...
Object.prototype.toString.call(new Date()); // '[object Date]'
// Now to have some fun:
const suspiciousDate = new Date();
suspiciousDate[Symbol.toStringTag] = 'window';
Object.prototype.toString.call(suspiciousDate); // wut!
