Vue.prototype.GLOBAL, the .global is defined at will or written in a prescribed way. I think what does it mean for some people to bring $?

 import global_ from "./components/Global"//
 Vue.prototype.GLOBAL = global_//Vue

this belongs to the Vue.$axios defined randomly by yourself

request for $http before angular is written mostly as distinct from variables
