angular.js - Can you tell whether the angularjs module is started?

Question

The module I use to start Angular in my application is asynchronous, so multiple files need to determine whether the module has been started. If it is not started, start it. If it is started, use it directly.
I would like to ask if AngularJS provides a detection mechanism

Answer 1

The question I asked makes no sense

Answer 2

angular.module('xxx',[]).run(function(){
    console.log('初始化完毕');
});

Answer 3

This can be found in the source code

if(!window.angular.bootstrap){
    angular.bootstrap(app, ['MyModule']);
}
