2. CLI Prompts:

This is a life-saving feature for developers who tend to forget routing or like activities. The new CLI prompts you to add routing or take advantage of other in-built SCSS support. So, now if you are running commands as ng new or ng add, you will not end up terminating the command if you happen to forget routing. You can also select between different stylesheet formats including CSS, SCSS, and SAAS. The best part is its ability to get customized.
