Overview

The challenge

Users should be able to:

• View the optimal layout for the app depending on their device's screen size
• See hover states for all interactive elements on the page
• Create, Read, Update, and Delete comments and replies
• Upvote and downvote comments
• Bonus: If you're building a purely front-end project, use localStorage to save the current state in the browser that persists when the browser is refreshed.
• Bonus: Instead of using the createdAt strings from the data.json file, try using timestamps and dynamically track the time since the comment or reply was posted.

? (commentsCopy[parentIndex].replies[index].content=text)
: (commentsCopy[index].content=text);state.comments=[...commentsCopy];}

useEffect(()=>{if(mode==="reply"){setInput(`@${replyingTo} `);setInputRef();}},[mode]);
