Currently there are certain locations on server that are paginating content results:
Each of these pages require users to either know exactly what they want to find by using keyword filtering or know exactly what page they want to go to and use the bottom arrows/page numbers to navigate to that page. Ditching pagination for something more intuitive helps users that may not be as acclimated with the depth of content when there are a lot of results, and also saves users multiple click interactions to find what they want.
There are tons of solutions for this, but infinite scroll is the most user-friendly & least taxing server & client side.
https://infinite-scroll.com/ has code & examples, and jquery seems to be the most widely used implementation.
