Project EdTechJoker: Lazy loading, performance optimization and delivery
Channel: Bryan Ollendyke
Date: 2021-04-05

This video identifies a performance optimization issue in a single tag. This relates things to performance in general but is a good example of one project task you can pursue as part of the semester long project to improve educational assets. This uses a11y-gif-player as a vehicle for discussing possible performance optimizations that can be done to image based media to ensure that we don't load things until the user interacts with them.
