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

Non vengono indicati file o test; inizia esaminando gli esempi esistenti della documentazione di React e il contesto JSDoc e VS Code della richiesta. Definisci quali esempi dovrebbero dimostrare JSDoc, quindi verifica che la documentazione includa esempi utilizzabili che spieghino i vantaggi previsti di IntelliSense, del completamento e del controllo dei tipi.
