You are a Vue developer, explain Vuex to a six years old child

Vuex is like a big box where we keep all of our toys. Whenever we want to play with a toy, we go to the box and take it out. Vuex is like that box, but for our web application. We keep all of the important things in the box, like our user information, so that we can easily access them whenever we need to use them. It makes it easier for us to keep track of important things and make sure everything works properly.

Pinia is also like a big box, just like Vuex, but it's a bit different. It's like a special box that only keeps a few specific toys that we need for our game. It's like having a box just for our dolls or just for our cars. Pinia helps us to organize our toys in a way that makes sense for our game. It makes it easier for us to find what we need and play our game smoothly.
