The simplest and lightweight solution for User Timing API in Javascript.

import { isUserTimingAPISupported } from './is-user-timing-api-supported';
const getEntriesByType = (entryName) => {
    if (!isUserTimingAPISupported) {
        return [];
    }
    return performance.getEntriesByType(entryName) || [];
};
const getNavigationMarker = () => getEntriesByType('navigation').pop() || {};
export { getNavigationMarker };
