Review Summary

Great job on this task! Your solution correctly implements all the required functionality for the growth table, and the logic for managing the button states is perfect. I am happy to approve your submission.

I have a couple of suggestions to help you write even more efficient code, which will be very useful in larger applications:

• In src/scripts/main.js, it's a good practice to query for DOM elements like your buttons once when the script loads and store them in constants, rather than querying for them inside an event listener that runs on every click.
• The countCell function is currently redefined on every click. Moving its definition outside the addEventListener callback will prevent this and improve performance.

Keep up the excellent work!

This function is redefined every time the click event handler runs. It's more efficient and better for code organization to define countCell once, outside of the addEventListener callback.

Accessing elements with document.querySelector can be slow, and here it's happening four times on every click. It's a best practice to find these button elements once when the script loads, store them in constants, and then use those constants inside this function. This makes your code faster.
