How to start using is_js CDN
// Include the is_js library from the CDN
const isJs = (() => {
const script = document.createElement('script');
script.src = 'https://cdn.cdnhub.io/is_js/0.9.0/is.min.js';
script.async = true;
script.onload = () => {
window.is = window.is || {};
return window.is;
};
document.head.appendChild(script);
return new Promise(resolve => {
window.onload = () => {
if (typeof window.is === 'object') {
resolve(window.is);
}
};
});
})();
// Usage example
async function checkBrowserSupport() {
const browserSupportsWebComponents = await isJs.is('features.custom-elements');
if (browserSupportsWebComponents) {
console.log('Browser supports custom elements.');
} else {
console.log('Browser does not support custom elements.');
}
}
checkBrowserSupport();
