Library now works for AngularJS, using its $scope events mechanism.
Lib is in ES2015 syntax, so if you need it in ES5, please use babel to transpile.
Library have now 3 types of functions:
wait (eventName) - to wait when event has been executed
exec (funciton) - executes some code
broadcast (eventName) - broadcasts the event
When you create the sequence you are starting some journey. In which you could use 3 types of functions: wait, exec, broadcast.
var sequence =newSequence(this.$scope);
Here you are waiting for the event userAction-1 from any angular component, then when event has been fired you are going to the next step - waiting for the event userScroll-1. When you pass second parameter in wait function if means that you are calling method userSCroll-1 in self.scrollManager object and this method is getting callback as parameter. And when callback will be fired from this object next sequence method will be executed.
