/* Enhancements to the Twitter Scraping Script:

This update to the script introduces a more robust mechanism for extracting detailed interaction data from tweets as they are scraped from Twitter. Previously, the script focused on collecting basic content such as the tweet's text. Now, it has been augmented to include a comprehensive extraction of interaction metrics, including replies, reposts, likes, bookmarks, and views, for each tweet.

Key Changes:

1. Improved Data Extraction:
   - The script now searches through all elements within a tweet that have an `aria-label` attribute, filtering for labels that contain key interaction terms (replies, reposts, likes, bookmarks, views). This ensures that only relevant `aria-labels` are considered for data extraction.

2. Flexible Interaction Data Parsing:
   - A new function, `extractInteractionDataFromString`, has been added. It uses regular expressions to parse the consolidated interaction data string found in the `aria-label`. This approach allows for a more accurate extraction of numeric values corresponding to each type of interaction, regardless of slight variations in the `aria-label` text format.

3. Auxiliary Function for Numeric Extraction:
   - An auxiliary function, `extractNumberForKeyword`, has been introduced to extract numbers based on specific keywords within the interaction data string. This function enhances the script's ability to accurately parse and convert interaction metrics from textual descriptions to numeric values.

4. MutationObserver Integration:
   - The use of `MutationObserver` remains to monitor DOM changes dynamically, ensuring that the script continues to capture tweets as the user scrolls through Twitter. The observer triggers the `updateTweets` function to process newly loaded tweets.

5. Efficient Tweet Uniqueness Check:
   - The logic for determining whether a tweet is new (and thus should be added to the collection) has been refined. This check now ensures that duplicates are effectively filtered out, maintaining the integrity of the scraped data set.

6. JSON Download Functionality:
   - The final step of the script, which involves compiling the scraped tweets into a JSON file and downloading it, has been preserved. This feature provides users with a convenient way to export the collected data for further analysis or archiving.

By implementing these enhancements, the script now offers a comprehensive solution for scraping detailed interaction data from X, making it a valuable tool for social media analysis, research, and data collection projects.
