Angular Universal is used for server-side rendering and pre-rendering Angular applications, providing content on the page for quick interaction and SEO benefits. Pre-rendering with Angular Universal allows developers to deploy their applications to Netlify with ease. To achieve this, two main steps are required: adding Angular Universal using the `ng add` command and running a script to pre-render routes. The pre-rendering process involves managing server-side rendering and deployment to a CDN like Netlify.
