5. Reduce boilerplate in Guards [Functional Router Guards]
Let’s understand this concept in a better way with one example of defining guards, verifying details, whether the user has logged in or not.

8. CDS Listbox
CDK stands for Component Dev Kit that offers different behavior primitives, helping in building UI components. In angular v15, it gets new primitive called CDK Listbox, enabling developers to customize Listbox interactions drawn up by WAI-ARIA Listbox pattern based on requirements.
9. Extended esbuild support
In angular 14 updaet, there was enablement to an experimental support esbuild — a faster javascript bundler, enabling quick build done with simplifhing in the pipeline
