In basic terms, Angular bootstrapping allows experts to start or launch an Angular application. Both manual and automated bootstrapping are supported by Angular. Let’s have a look at the differences between the two.
Manual bootstrapping: It provides professionals more flexibility in terms of how and when they need to initialize the Angular app. It comes in handy in situations where experts need to complete other activities and processes before Angular builds the page.
Automatic bootstrapping: If professionals want Angular to automatically bootstrap the application, automatic bootstrapping may be used to add the ng-app directive to the application’s root, commonly on the tag. When Angular detects the ng-app directive, it imports the related module and builds the DOM.
