         ## Apply to be included as a recommended React framework
 
         _This form is for framework authors to apply to be included as a recommended [React framework](https://react.dev/learn/start-a-new-react-project). If you are not a framework author, please contact the authors before submitting._
-        
+
         Our goal when recommending a framework is to start developers with a React project that solves common problems like code splitting, data fetching, routing, and HTML generation without any extra work later. We believe this will allow users to get started quickly with React, and scale their app to production.
-        
+
         While we understand that many frameworks may want to be featured, this page is not a place to advertise every possible React framework or all frameworks that you can add React to. There are many great frameworks that offer support for React that are not listed in our guides. The frameworks we recommend have invested significantly in the React ecosystem, and collaborated with the React team to be compatible with our [full-stack React architecture vision](https://react.dev/learn/start-a-new-react-project#which-features-make-up-the-react-teams-full-stack-architecture-vision).
-        
+
         To be included, frameworks must meet the following criteria:
-        
+
         - **Free & open-source**: must be open source and free to use.
         - **Well maintained**. must be actively maintained, providing bug fixes and improvements.
         - **Active community**: must have a sufficiently large and active community to support users.
@@ -25,7 +25,7 @@ body:
         - **Developer experience**. must allow developers to be productive by supporting features like Fast Refresh.
         - **User experience**. must provide built-in support for common problems like routing and data-fetching.
         - **Compatible with our future vision for React**. React evolves over time, and frameworks that do not align with React’s direction risk isolating their users from the main React ecosystem over time. To be included on this page we must feel confident that the framework is setting its users up for success with React over time.
-        
+
         Please note, we have reviewed most of the popular frameworks available today, so it is unlikely we have not considered your framework already. But if you think we missed something, please complete the application below.

 React 18의 많은 기능은 강력한 새 기능들을 제공하는 배후의 변경 사항인 concurrent 렌더러를 기반으로 구축되었습니다. concurrent 렌더러는 선택 사항으로, concurrent 기능을 사용할 때만 활성화할 수 있지만 사람들이 애플리케이션을 빌드하는 방식에 큰 영향을 미칠 것으로 예상됩니다.
