Note that the development build is not optimized. To create a production build, run npm run build.

运行npm run build可以创建一个优化的生产版本，而开发版本则没有进行优化。在React Redux Saga TODO应用程序中，可以使用该命令来创建生产版本。另外，可以使用nvm命令来安装和管理不同版本的Node.js，具体命令如下：

nvm -v // 查看nvm版本
nvm install 14.16.0 // 下载指定版本
nvm install latest // 安装最新版本
vm use 14.16.0 // 使用指定版本
nvm ls // 查看已经安装的nodejs版本
node -v // 查看nodejs版本

As an AI language model, I do not have the ability to run npm run build or any other command-line interface tools. However, I can provide you with information about the statement you mentioned.

The statement "Note that the development build is not optimized. To create a production build, run npm run build" is a common message that developers encounter when working with the Node.js package manager (npm) and building applications using frameworks such as React or Angular.

In essence, the statement is a reminder that the development build of your application is not optimized for performance and should not be used in a production environment. Instead, developers are advised to run the "npm run build" command to create a production build of their application, which is optimized for performance and can be deployed to a production server.

In summary, if you want to optimize your application for production use, you should run the "npm run build" command.
