Javascript – Check for web component support

I’d like to test the browser support of web components. Thus I thought of doing it using:

if('define' in customElements) return true;

Is there a better or different way of doing this?

    1. Maybe this: Detect if dom element is custom web component or html element

    2. in most cases only web component will have shadow dom, might also be an option

    You can also do this for better approach.

    if (window.customElements) {
  // Custom elements are supported
  return true;
} else {
  // Custom elements are not supported
  return false;
}
