I am very glad that you have reached this point, this means that you already know what Vue.js is, and if someone asks you whether it is a tool, a library, or a framework, you certainly will find an answer. You also know how to start an application using Vue.js and you know how to use Vue's features in an already existing project. You played around with some really nice projects that are written in Vue.js and you started developing some of your own! Now you do not just go shopping, now you go shopping with a shopping list created by you using Vue.js! Now you don't need to steal your tomato timer from the kitchen to use it as a Pomodoro timer while working; you can use your own digital Pomodoro timer made with Vue.js. And, last but not the least, now you can insert random kittens in your JavaScript application also using Vue.js.

In the next chapter, we will cover the behind the scenes of Vue, how and why does it work, and the architectural patterns it uses. Each of the concepts will be wrapped up with an example to demonstrate it. Then we will be ready to put our hands deep into the code and to improve our applications taking them to the state of awesomeness.
