CODE EXAMPLE FOR JAVASCRIPT

render twice react

`React intentionally remounts your components in development 
to help you find bugs. You can turn off Strict Mode to opt out of the development behavior,
but we recommend keeping it on.` (Docs)

// To disable: Remove <React.StrictMode> or <StrictMode>
root.render( <React.StrictMode>
    	       <App />
             </React.StrictMode>);
// After:
root.render( <App /> );
