• Use props to make a dynamic component template
• Pass props from a parent component to a child component

Previously, we had been importing some data directly into each component that needed it using import. When we're working with React, we'll often access data by passing it down as a prop rather than importing it. This will be particularly true once we start working with data from external sources, such as APIs.

In this lab, you'll write React components and render them dynamically based on props they receive from their parent components. This will enable us to use components as templates with the ability to render variable content.

We'll continue building the portfolio site we started in the previous labs, and make the content dynamic by using props.

Here is an image of what we want once we are finished:

...and here is a tree view of our component parent-child structure:

└── App
    ├── NavBar
    ├── Home
    └── About
        └── Links

It's recommended that you run npm start and work on this in the browser before running tests. Try to get your app to match the demo! Once you've built out the components below, run npm test to see if your code passes the tests.

In the App component, pass down data from the user object as props to the Home component so that it renders correctly. There is some starter code for you in the Home component that should give you a clue as to what props this component takes in.

App should also pass down a prop of bio to the About component.

Finally, App should also pass down the github and linkedin links to the About component, so that About can pass those props down to the Links component you will create.

Update the About component so that:

• If a prop of bio is passed to this component, it is displayed inside of a <p> tag
• If a prop of bio is not passed down, or if bio is an empty string, don't display the <p> tag
• Hint: you'll need to do some conditional rendering here to determine whether or not to display the <p> tag

Create a new component called Links. In this component, display the following:

• an <h3> element with the text of "Links"
• an <a> element with its href and text content set to URL of the user's Github link, passed down as a prop
• a second <a> element with its href and text content set to URL of the user's LinkedIn link, passed down as a prop
• Hint: make sure your <a> tags display the URL of the user's links as their text content so that it matches the demo image above
