It covers the new zoneless change detection, deferrable views with @defer, signal-based reactivity, and OnPush strategies. You get practical examples for lazy loading routes, using trackBy in loops, and optimizing bundle sizes. The code snippets are clean and show both what to avoid and what to do instead. If you're dealing with slow Angular apps or bloated bundles, this gives Claude enough context to suggest actual fixes instead of generic advice. It assumes you're working with modern Angular, so older projects might need different approaches.
