React Router v6 implements routing matching through the Routes component and path ranking system. It compares the current URL to the defined routing path and selects the best match based on the path specificity (more specific paths rank higher), thereby conditionally rendering the corresponding UI components. This mechanism ensures that even if wildcard routing exists, more precise paths can be matched first, avoiding unnecessary component rendering.
