| Load the Library
There is one theory that Global Functions should not be define in JavaScript because if we define Global function in JavaScript then is should be easily overwritten or destroyed by any other scripts. To overcome this types of issue AngularJS module reduces the problem by keeping all functions local to the module.
Now another topic which we define here is that when we load the library and where should we place the Script. It is very common in HTML applications to place scripts at the end of < body> elements. And we also recommended you to load the AngularJS library either in the or at the start of tag.
And reason could be because calls to angular.module can be compiled after the library has been loaded.
