Veda Bites are swipeable micro-lessons — each one teaches exactly one idea. Here's a taste from this kit; the app has the full deck.
One URL, one component — no reload.
Routing in React connects a URL path to a component, so the app swaps views instantly without refreshing the page.
↳ Routing turns a single-page app into a multi-view experience driven by the URL.
Speak the routing language first.
↳ Router enables routing; Route defines paths; Link navigates; params make paths dynamic.
Why not just use <a>?
↳ Use <Link> for internal navigation to avoid reloads; use <a> only for external sites.
Routing in React lets a single-page application show different views based on the URL without a full page reload. It maps URL paths to components, enabling navigation, nested layouts, and dynamic parameters in React apps...

16 questions laddered from warm-up to topper-level, each with an explanation. A taste:
What does routing primarily map in a React app?
BeginnerA URL path to a React component
Routing pairs a URL path with a component so the app can show different views for different URLs.
In a routed React app, what acts as the source of truth for what is rendered?
BeginnerThe URL in the address bar
Routing flips the usual model: the URL drives rendering, not component state.
Which browser API does client-side routing use to change the URL without a full page reload?
BeginnerThe History API
Client-side routing calls methods like `history.pushState` to update the URL while React re-renders.
Which element should you use for in-app navigation to avoid a full page reload?
Beginner`<Link>`
`` intercepts the click and navigates client-side; a plain `` triggers a full reload and loses React state.
