One of my more grueling projects. The site had 2 large JavaScript files, mostly comprised of spaghetti code jQuery written by a PHP guy. I got rid of almost every single scrap of jQuery I could find, rewrote it as ES6+ JS, broke everything out into organized modules so each page got code that was actually relevant and not one giant bundle, and installed Node and Webpack so third party libraries didn't have to be manually downloaded and added to the directory anymore. All before AI was there to assist and make nitty gritty work like this easier. Just docs and Stack Overflow. Man, I feel old.
