Life cycle events are events that are triggered inside a web component when it reaches a certain stage of execution. These stages reflect the overall process of creating a web component and can be controlled with the help of life cycle callback methods. Life cycle callback methods are hooks or interfaces that get called back whenever a Web Component goes through these life cycle events.

Let me explain this with the help of an example. Suppose you have a shoe that you would like to wear. There may be certain events associated with the life cycle of this shoe. Let's say you want to wear it. You put your foot in and tie the lace. This triggers an event called lacesTied(). Now, you as a user who is wearing this shoe may choose to act on it. You can write a conditional block to check whether lacesTiedStrength > 100 or whether shoeSize < requiredShoeSize. It depends on what you want to do. Similarly, there are life cycle callback methods associated with a Web Component that help the user capture certain execution states and write code effectively.
