In this section, you will learn how to create your own custom UI5 Web Components packages and develop your own UI5 Web Components. This section will cover how UI5 Web Components work, how to manage their states, and understand their lifecycle.
All UI5 Web Components are built on top of the UI5Element class, which extends HTMLElement.
The entire API provided by UI5 Web Components can be condensed into a set of base classes, decorators, lifecycle hooks, and rendering methods.
UI5Element is a class provided by the @ui5/webcomponents-base package. This class enhances the HTMLElement class by adding basic state management functionality and runtime context to all UI5 Web Components.
