So what is it?

This repository is the official router for Vue.js, specifically version 4 of Vue Router which works with Vue 3. In web development, a router is the piece of software that decides what content to show when a user navigates to different parts of a website or app, for example moving from a home page to a profile page without the browser reloading the whole site. Vue Router is an open-source project maintained under an MIT license, meaning anyone can use it freely. Its ongoing development is funded by sponsors rather than a company, and the README lists several gold, silver, and bronze sponsors who support the work financially. If you want to add Vue Router to a project, the README points to three quick options: loading it directly via a CDN link in an HTML file, trying it in an online sandbox, or installing it through the npm package manager with a single command. Full documentation is hosted at router.vuejs.org. If you previously used Vue Router 3 with Vue 2, there is a migration guide available on the documentation site explaining what changed. The older version is maintained in a separate repository. The README is short and focused, directing readers to external documentation for deeper detail rather than explaining everything in one place.

Using Vue Router 4, how do I add a navigation guard that checks if a user is logged in and redirects them to /login if they try to visit a protected page?

Show me how to use Vue Router 4's lazy loading syntax to split my app so each route loads its own JavaScript chunk only when the user visits that page.
