Passing data from parent to child component is a basic mechanism in a component-oriented architecture. In Blazor, there are several ways parent and child components communicate with each other.
Event callbacks complete the Blazor component communication circle by allowing a child component to send information to its parent component when the user triggers an action.
Component rendering is a core mechanic of Blazor applications turning C# components into HTML and CSS. Lifecycle methods allow us to execute custom code synchronously or asynchronously.
