*
* This component isn't part of CoreComponentsModule to prevent circular dependencies. If you want to use it,
* you need to import CoreCompileHtmlComponentsModule.
+ *
+ * You can provide some Javascript code (as text) to be executed inside the component. The context of the javascript code (this)
+ * will be the component instance created to compile the template. This means your javascript code can interact with the template.
+ * The component instance will have most of the providers so you can use them in the javascript code. E.g. if you want to use
+ * CoreAppProvider, you can do it with "this.CoreAppProvider".
