What is an AOT compilation in Angular?
Ahead-of-Time (AOT) compilation in Angular refers to the process of converting Angular application code into efficient JavaScript code during the build phase, before the application is deployed to the client's browser. This is in contrast to Just-in-Time (JIT) compilation, where the Angular code is compiled in the client's browser at runtime.

Advantages of AOT compilation in Angular include:
Faster Loading: AOT compilation reduces the size of JavaScript bundles and eliminates the need for the client's browser to perform compilation. This results in faster initial loading times for the application.
Better Performance: AOT-compiled code tends to execute faster because it has already been optimized during the build process. This leads to smoother and more responsive user experiences.

Error Detection: AOT compilation catches template errors and other potential issues during the build phase, allowing developers to address them before deploying the application.
Optimized Bundling: AOT compilation enables tree-shaking, which removes unused code from the application bundles, resulting in smaller bundle sizes and improved efficiency.
