Using event handler context and parameters
In this section, you'll learn about React components that bind their event handler contexts and how you can pass data into event handlers. Having the right context is important for React event handler functions because they usually need access to component properties or state.

import * as ReactDOM from "react-dom";

{ id: 1, name: "...
