Add samples) react components with JSDocs!

Please add samples on JSDocs with react, a lot programmers including me need IntelliSense and other benefits like auto-completion and type-checking as well. Migration over to TypeScript is not ideal if you have large code base. Adding a JSDoc comment is the easiest way of getting a lot of TypeScript tooling without configuring any code at all. On top of that vscode already supports it just by turning on in the settings
"javascript.implicitProjectConfig.checkJs": true

It even provides comment template for JavaScript functions when you type/**

That's way I think reactjs docs should provide examples on this

未指定文件或测试；首先查看现有的 React 文档示例，以及请求中的 JSDoc 和 VS Code 上下文。确定哪些示例应演示 JSDoc，然后验证文档包含可用的示例，解释 IntelliSense、补全和类型检查的预期好处。
