Learn React 18 with Redux Toolkit – Full Tutorial for Beginners
Learn how to use React version 18 and Redux Toolkit in this full course for beginners. React is a free and open-source front-end JavaScript library for building user interfaces based on components. 

Here’s the list of what’s new in this preview:

• Razor Components renamed back to server-side Blazor
• Client-side Blazor on WebAssembly now in official preview
• Resolve components based on @using
• _Imports.razor
• New component item template
• Reconnection to the same server
• Stateful reconnection after prerendering
• Render stateful interactive components from Razor pages and views
• Detect when the app is prerendering
• Configure the SignalR client for server-side Blazor apps
• Improved SignalR reconnect features
• Configure SignalR client for server-side Blazor apps
• Additional options for MVC service registration
• Endpoint routing updates
• New template for gRPC
• Design-time build for gRPC
• New Worker SDK 

OVERVIEW
Razor components are specific building blocks within the Blazor framework. They can perform many roles: representing a specific piece of the user interface, a view component, or a tag helper; or representing a layout or an entire page. In Razor Components Succinctly, you will explore how to create and work with both simple and advanced Razor components. Longtime Succinctly author Ed Freitas will show you how to write a basic component using one-way data binding and events, and then two-way data binding, event callbacks, life cycle methods, and component references. Finally, you'll see how to enable component reuse by creating a component template.
