An ES spec-compliant Object.hasOwn shim. Invoke its "shim" method to shim Object.hasOwn if it is unavailable or noncompliant.

This package implements the es-shim API interface. It works in an ES3-supported environment and complies with the spec.

Most common usage:
``js
var assert = require('assert');
var hasOwn = require('object.hasown');

var obj = { a: 1, b: 2 };

assert(hasOwn(obj, 'a'));
assert(hasOwn(obj, 'b'));
assert('toString' in obj && !hasOwn(obj, 'toString'));

if (!Object.hasOwn) {
hasOwn.shim();
}

assert.deepEqual(Object.hasOwn(obj, 'a'), hasOwn(obj, 'a'));
`
