docs: Deployment guide for CLI - #19839

xcopy -> copy

xcopy->copy

--environment=prod -> --target=prod

These two are actually different: https://github.com/angular/angular-cli/wiki/build#build-targets-and-environment-files

I just compared --environment=prod vs --environment=dev and they enable/disable prodMod exactly as I said and expected.

So do --target=production vs --target=development. But the --environment flag is way more intuitive, especially after looking at main.ts

if (environment.production) {
  enableProdMode();
}

Why should I change from --environment to --target? The wiki page is not helping me understand.

Note that I mention --environment here only to talk about enableProd. I'm not talking about any of the other optimizations that would be enabled by --target=production. So I think this text is correct.

You're right, I misunderstood what was being talked about here.

ng build also deletes the directory, it just outputs new files there after.

You can use ng build --watch to continuously generate files.

We will deprecate the quickstart, we shouldn't name it anymore.
