Unity Awake vs Start Event - Differences and Similarity

Unity MonoBehaviour offers different magic events that you can attach to any GameObject. In this unity tutorial I will explain awake or start events as they both mostly use for assignment purposes.

Awake:  Awake is invoked when the MonoBehaviour is created. You may view it as your default constructor

Start: Start event executes after all initialization is done and the first frame for the behavior is about to run. Start runs right before the Update event.

Similarity:

Start/Awake are called exactly once in the lifetime of the script.
