This class is a wrapper around the ubiquitous native Entity class of Drupal 8 (Drupal\Core\Entity\Entity) from which all specialized Entity objects (Nodes, Paragraphs, etc.) in Drupal are derived. It can be used instead as a more convenient replacement. First and foremost, this is benefical, because you can use DrupalX's field name mapping with this class - in consequence allowing you to often omit the repetitive field_ prefix. In addition, this class greatly simplifies the process of searching for entities (Entity query), rendering of specific entity fields and much more.
