Dependency Injection in Drupal 8

Here are the important nuggets: DI is a design pattern used in programming. DI uses composition. DI achieves inversion of control. Dependency == service that your class needs == object of a certain type. Inject == provide == compose == assemble. Container == service container == dependency container. Instead of using  \Drupal::service('foo_service') , get the service from the  $container  if using a class. And the important reasons: Externalizing dependencies makes code easier to test. It allows dependencies to be replaced without interfering with other functionality. Retrieving dependencies from the container is better for performance. Services: node.grant_storage The easiest examples to find are services that have arguments, because you can search *.services.yml files for the word "arguments". In  node.services.yml  for example, there is this entry: node.grant_storage: class: Drupal\node\NodeGrantDatabaseStorage argument...
