Leveraging the Event Loop for Blazing-Fast Applications!

Abstract

Can the Microtask Queue help you improve your performances by 100x? It turns out, it can!

Years ago I made my own implementation of signals, capable of updating 300k times the DOM in circa 600ms. Leveraging the Microtask Queue, I was able to bring that number down to 6ms, effectively improving performances by 100x. I wanna share how the Microtask Queue works and how you can leverage the Event Loop to improve performances and why years later these tips are still relevant.
