Proactor pattern

Okay, so let's pretend you have a really cool toy that can do lots of things, but it's a bit complicated to use. You have to press buttons and wait for it to finish before you can do something else. This can be frustrating because sometimes you want to play with it more quickly.

Now, imagine that the toy has a special helper called a "proactor" that can press all the buttons for you and tell you when it's done. It's like having a personal assistant for your toy!

The proactor works by watching for things that need to be done and then doing them in the right order. So, when you want to do something with your toy, you tell the proactor what you want to do, and then it takes care of everything else.

For example, let's say you want your toy to take a picture. You would tell the proactor to get the camera ready, then take the picture, and finally, show you the picture. The proactor would do all of these things for you, so you don't need to worry about pressing the right buttons in the right order.

Overall, the proactor pattern is like having a really helpful friend who takes care of all the complicated stuff for you so you can focus on having fun with your toy.
