Let's now implement removing a purchase. We already have a remove link, we create it with this line:
createCell(tr, 'remove', 'remove');
I remind you that the createCell function
returns the created cell. This means that various
operations can be performed with this cell. For
example, let's bind a click handler to it:
let remove = createCell(tr, 'remove', 'remove');
remove.addEventListener('click', function() {
// let's remove a table row
});
Intermediate variable can be omitted:
createCell(tr, 'remove', 'remove').addEventListener('click', function() {
// let's remove a table row
});
Write the missing code to remove a table row.
Add a recountTotal function invocation
at the right place so that removing the
purchase updates the total sum.
