minor edit suggestions for React Foundations

[dbry23]

In Chapter 6 Displaying Data with Props (https://nextjs.org/learn/react-foundations/displaying-data-with-props), in the code sample where the array names is added, you should probably not have the names.map() code present because it's added and described in the next code sample.

In Chapter 7 Adding Interactivity with State (https://nextjs.org/learn/react-foundations/updating-state), in the code sample that follows "Then, you can check the initial state is working..." there are two issues:

• The text for the <button> should be Likes ({likes}) (like the next code sample) instead of Like({likes}) ("Like" instead of "Likes", no space before parenthesis)
• The // ... lines are highlighted, but I don't think that was the intention. It should probably just be the <button> line.
