My Machine: MAC PRO M1 and I prefer zsh over bash

If you are using Angular and want to have fun with its powerful cli, You may need the Angular completion to discover all commands and their options with a TAB press in your terminal.

Here is how you can activate it

 ng completion

So simple! but once you want to try it for the first time, zsh is not loading the auto-completions

Here is the fix

nano ~/.zshrc

And add these two lines

autoload -Uz compinit
compinit

Everything should work now!
