React.js library is all about splitting the app into several components. Each Component has its own lifecycle. React provides us some in-built methods that we can override at particular stages in the life-cycle of the component.

import { isDOMComponent } from 'react-dom/test-utils';
// Defining our App Component
const App = () => {
  // Function to demonstrate isDOMcomponent() method
  function func() {
    var a = isDOMComponent(el);
    console.log("The Following element is a DOM component :", a);
  const el = <div>
  // Returning our JSX code
  return <>
      <div id='el'>
          <button onClick={func}>Click Here !!</button>
// Exporting your Default App Component
export default App
