Transitioning from D7 to D8 for Front End Developers (No, this isn’t another Twig talk)

The transition from Drupal 7 to Drupal 8 can be daunting for front end developers. With the shift towards modern PHP standards and OOP, even front end devs who were comfortable with D7’s preprocessing functions, theme functions, and hook_alters() may now find themselves with many questions. How do I make links without the l() function? How do I get an entity from a path without menu_get_object() or arg()? More importantly, how do I learn where to find this information on my own? This knowledge isn't just for back end developers -- it’s a necessary component in the arsenal of any front end developer who wants to use the theme layer to its full potential. This session will address how to make the shift to object-oriented design patterns in a way that is relevant to front end developers, and will provide examples on how to find the answers they need right in the source code.
