Working with custom elements in React

Custom HTML elements allow developers to create uniquely defined HTML elements with customizable behavior, offering benefits such as encapsulating complex functionalities, improving code organization, and enhancing reusability. Despite their advantages, integrating custom elements with React has posed challenges, primarily because React previously treated unrecognized props as attributes rather than properties. This discrepancy often led to issues when using custom elements with React, as setting an attribute might not trigger the same logic as setting a property. However, React 19 has introduced changes that address these challenges by distinguishing between props and attributes more effectively, particularly in server- and client-side rendering contexts. With these updates, developers can better leverage custom HTML elements within React applications, making the integration process smoother and more reliable.
