Event-driven messaging
Event-driven messaging is like being invited to a party. Just like how your friend sends you an invitation to their party, event-driven messaging also sends messages to different parts of a computer program.
Imagine you are playing a game on your computer, and suddenly you complete a level. The computer sends a message to the game telling it that you have succeeded in the level. This is called an event.
An event is when something important happens in a computer program. When an event happens, it can trigger other parts of the program to do something else. This is where event-driven messaging comes into play.
Think of each part of the program as a person at the party. They all have their own tasks to do, but they need to know when something important happens so they can react to it. In event-driven messaging, the different parts of the program can “listen” for messages and react to them.
So, going back to the game example, when you complete a level, the game sends a message to other parts of the program telling them that you have succeeded. This message is like a notification that something important has happened.
The other parts of the program that are waiting for this message can then react to it. For example, the program might show a congratulatory message, unlock new levels, or give you special points.
In summary, event-driven messaging is like sending invitations to different parts of a computer program. When an important event happens, the program sends out messages to other parts of the program. These messages trigger different reactions and help the different parts of the program work together.
