The `ng-app` attribute represents an Angular directive, named `ngApp` (Angular uses `kebab-case` for
77+
its custom attributes and `camelCase` for the corresponding directives which implement them). This
78+
directive is used to flag the HTML element that Angular should consider to be the root element of
79+
our application. This gives application developers the freedom to tell Angular if the entire HTML
80+
page or only a portion of it should be treated as the AngularJS application.
