All components of a Vue application must be able to exchange data. In this part of Vue, we will look at how this communication is realized via so-called properties and events.js series.
A Vue application is divided into different components, each with its own logic and its own user interface. This keeps the code clear, reusable and maintainable. However, this also brings with it a new problem: each component has its own data.
In order to keep each other up to date with data changes, the components must communicate with each other. This communication can take place in two directions: from the surrounding parent component to the child component and, in the case of important data changes in the child component, also in the opposite direction.
