Create val
const assert = require('assert');

const $defineProperty = require('es-define-property');

if ($defineProperty) {
    assert.equal($defineProperty, Object.defineProperty);
} else if (Object.defineProperty) {
    assert.equal($defineProperty, false, 'this is IE 8');
} else {
    assert.equal($defineProperty, false, 'this is an ES3 engine');
}

Simply clone the repo, npm install, and run npm test
