Switching over to building the table with JS — wp.template.
We are now using the same JS template for existing rows and newly
generated rows on the fly — this should simplify things moving forward.
I’ve also started building stuff in an external JS file rather than
straight on the page. Will continue migrating things to it and
localizing as needed.
Saved ( 2 * displayed tax rates - 1 ) db queries per page load by doing
the locations all in one query and then parceling them out in php.
More coming.
