We're now ready to get started! Inside our new project directory, create a new index.html file. Inside it, add in the following boilerplate.
<!DOCTYPE html><html lang="en"><head> <meta charset="UTF-8"> <meta name="viewport" content="width=device-width, initial-scale=1.0"> <meta http-equiv="X-UA-Compatible" content="ie=edge"> <title>Hobnob</title></head><body></body></html>
We will be using two libraries: react and react-dom. react is the base package that allows you to define components; the react-dom package allows you to translate React components in the Virtual DOM to DOM elements, and mount those DOM nodes into the DOM itself.
