It's a better practice to "attach event listener via JS" than "mixing JS code in HTML".

added event listener via JS.

It is a good practice to save sanitized or pre-processed values in some variables first
- to avoid calling .trim() repeatedly, and
- to reduce the chance of accidently using the raw value.
The book's page property can still be assigned some invalid page count.

Author

AdnaanA Dec 10, 2025

we can clean the values once and store them in variables: instead of the above code we could do
const titleValue = bookTitle.value.trim();
const authorValue = author.value.trim();
const pagesValue = pages.value.trim();

and we can over come the page being assigned invalid count we can do this

const pagesNumber = Number(pagesValue);
if (!Number.isInteger(pagesNumber) || pagesNumber <= 0) {
alert("Please enter a valid positive page count!");
return;
}

To clear the table before repopulating it, instead of deleting the table rows one by one, can you think of a more efficient way to remove all rows (except the <th>...</th>) in the table?

Author

AdnaanA Dec 9, 2025

we can use tbody.innerHTML = ''; to clear all rows efficiently.

however we have to use const row = tbody.insertRow(); to insert rows into tbody.

-                  deleteCell.appendChild(delBut);
+                  // delete button
+                  const deleteCell = row.insertCell(4);

Can you think of the pros and cons of these two approaches for creating cells within a row?

Keeping all the cell creation code in one location, like the original code does.
Scattering the cell creation code across different locations, like what you did.

Author

AdnaanA Dec 10, 2025

Keeping all cells created in one block is the best practice.
It is clearer, safer, easier to maintain, and less likely to produce bugs.
while
Scattered cell creation should only be used when absolutely necessary for conditional or dynamic table structures.
