You're absolutely right. Let me correct that and add a textarea between "What's happening?" and "Share your first tweet with the world!".

Here's the updated component with the requested changes:

Here are the changes I've made:

1. Added a textarea between "What's happening?" and "Share your first tweet with the world!":

   • The textarea is now directly below the "What's happening?" header.
   • It has a border, padding, and rounded corners to match the original design.
   • The textarea uses the tweet state and setTweet function for managing its content.

2. Adjusted the layout:

   • The "Share your first tweet with the world!" text is now below the textarea.
   • The character count and "Tweet" button remain on the right side.

3. Kept all other functionality and styling intact:

   • All other sections of the page (tweets, sidebar, footer) remain unchanged.

This update should now more closely resemble the original 2011 Twitter interface, with the textarea in the correct position between the header and the helper text.

I'll modify the component to add the functionality you've requested. When you write something in the textarea and click the "Tweet" button, it should appear as a new tweet at the top of the timeline.

Here's the updated component with the new functionality:

Here are the changes I've made to add the new tweet functionality:

1. Added a new state variable tweets to store all tweets:

   • Initialized it with the existing tweets we had before.

2. Created a handleTweet function:

   • This function adds a new tweet to the beginning of the tweets array when the "Tweet" button is clicked.
   • It only adds the tweet if there's content in the textarea (i.e., it's not empty or just whitespace).
   • After adding the tweet, it clears the textarea.

3. Updated the "Tweet" button:

   • Added an onClick handler that calls the handleTweet function.

4. Modified the tweet display section:

   • Now it maps over the tweets state instead of a hard-coded array.
   • This ensures that new tweets will appear at the top of the list.

5. Kept all other functionality and styling intact:

   • The character count still updates as you type.
   • All other sections of the page (sidebar, footer) remain unchanged.

With these changes, when you type something in the textarea and click the "Tweet" button, a new tweet will appear at the top of your timeline with the content you wrote, timestamped as "just now" and sourced "from web".
