Компиляция на первом месте (AOT)

The Angular ahead-of-time (AOT) compiler converts Angular HTML and TypeScript code into efficient JavaScript code during the build phase, before the browser downloads and runs that code. This is the best compilation mode for production environments, with decreased load time and increased performance compared to just-in-time (JIT) compilation.

By compiling your application using the ngc command-line tool, you can bootstrap directly to a module factory, so you do not need to include the Angular compiler in your JavaScript bundle.
