When learning, you should remember induction and the diagram at the beginning of this article. The observer mode is well understood, similar to email subscription and RSS subscription. When we browse some blogs or wikis, we often see RSS icons. This means that when you subscribe to the article, you will be notified in time if there are subsequent updates. In fact, in a nutshell, when an object changes, other objects that depend on the object will be notified and will change with it! Objects are a one-to-many relationship.
