Routes, Route, and Link

Concept

Routes, Route, and Link

react-router-dom's Routes and Route map a URL path to a component. Link renders navigable anchor tags without reloading the page.

By the end of this lesson
  • Explain the core idea behind Routes, Route, and Link.
  • Predict output before running a change.
  • Test one realistic and one unusual input.
  • Use the result to make the next decision.
