Similarly, Ext JS offers a declarative approach to building user interfaces. To bridge these two powerful frameworks, we have developed “Ext JS Reactor,” a package that seamlessly integrates Ext JS’s robust, feature-rich components into React-based applications. ...
It also now covers integrating forwardRef with functional components and class components.In this tutorial, we will go over the concept of forwarding refs in React and understand how it helps us manage interactions with the DOM. For a more engaging experience, we’ll cover how to create refs,...
