Tables, buttons, and dialogue boxes are just a few of the several front-end elements that are represented by Magento user interface (UI) components. Use pHTML templates with embedded JavaScript, XML layout, jQuery widgets, or UI elements to implement them. Magento encourages the use of UI elements to create a positive user experience and guarantee the seamless operation of all website functionalities, especially those requiring asynchronous startup. This makes it possible for a Magento 2 developer to build more complex UI components out of simpler ones (e.g., for the store checkout page).
