Drilling data from entities in drupal 8

Still new to this drupal 8 beast and trying to learn how to drill down data from entites. There are this magic getters and setters methods that get you data without need to write them. So

$entity->get("name"); can also be written like $entity->name;  
To make this more complext lets try to get data from entity reference field where one entity has reference field to taxonomy and basically we are getting a term name.

It would be like this


where we have $entity object loaded, then we go into field "field_positions_function" which is that magic getter, then we have entity property, then name magic getter and finally we get to value property.
