How does it work

Build modern web applications entirely in Java without the need to write HTML or JavaScript. Developers can focus on composing the user interface from components, connecting it to data sources, and reacting to user events, similar to building traditional desktop applications. The UI components are rendered in the browser as standard HTML, ensuring compatibility across modern browsers and devices

No, but I love #Java, and I hated the frontend until I met #Vaadin Flow, it was love at first sight. You don't need to be an advocate for a technology to know how powerful, friendly and fun it can be.
