docs: consider an optional React refresher on the MDX and React page

Have you read the Contributing Guidelines on issues?

• I have read the Contributing Guidelines on issues.

Description

The “MDX and React” guide introduces JSX and React components and already links to external MDX learning material near the top of the page.

Would a short, clearly optional React refresher help readers who can use Docusaurus but want to strengthen the render/state/effects model behind the examples?

Suggested resource: React interview preparation path

The public guide covers components, JSX, props and state, then moves into hooks/effects, state ownership, rendering behavior, testing, and performance trade-offs. If this kind of third-party companion is in scope, I would keep the documentation change to one optional sentence and only prepare a PR after maintainer confirmation.

Disclosure: I created and maintain FrontendAtlas and am affiliated with the linked resource. The guide is publicly readable without signing in; the broader platform includes optional paid features. No paid, affiliate, reciprocal, or special link treatment is requested. If interview-oriented preparation does not fit Docusaurus documentation, please close this request.

Self-service

• I'd be willing to address this documentation request myself.
