Examples

Error.isError(new Error('error')); // => true
Error.isError(new TypeError('error')); // => true
Error.isError(new DOMException('error')); // => true

Error.isError(null); // => false
Error.isError({}); // => false
Error.isError(Object.create(Error.prototype)); // => false

Warning

We have no bulletproof way to polyfill this Error.isError / check if the object is an error, so it's a rather naive implementation.
