In Ruby on Rails, callbacks are methods that are called at certain moments of an object's lifecycle. They are used to run code before or after specific events, such as saving, updating, or destroying a record. Callbacks are useful for handling tasks like data validation, setting default values, or triggering actions based on changes to a model.
Types of Callbacks
Before Callbacks: Run before an event occurs.
After Callbacks: Run after an event occurs.
Around Callbacks: Wraps around an event, allowing you to run code before and after the event.
