I've seen a few developers tout 'best practices' when wrapping angular components in anonymous functions. For example:

(function(){
     angular.controller('MyCtrl', [function(){
         // ... controller logic
     }]);
})()

What is the benefit of wrapping angularjs components in anonymous functions, if at all any?

回答1:

This is an immediately invoked function.

(function(){

})()

The above will declare an anonymous function that will be called immediately.
