Toptal's JavaScript Speed Coding Challenge invited creative solutions from the beginning. As the week played out, competitors got closer and closer to the maximum theoretical score. Then something unexpected happened...

Inspired by stale-while-revalidate cache control logic, modern sites implement stale-while-refresh logic on the UI side. Thankfully, React Hooks make this logic painlessly reusable across components.

The main artifact of all your work is most likely plain text files. So why don't you use Notepad to create them? Find out how the Language Server Protocol can transform text editors into code editors, without coupling.
