I will be completely honest, I don’t know performance dev tools as well as I probably should. I always find articles and talks on performance fascinating but when I come to learn stuff myself, my eyes often glaze over.
Articles like this are really helpful though because it’s a real world problem that I’m sure a lot of us have unwittingly done: animate properties that trigger layout such as positioning and margin etc. Dave discovered that and fixed it thanks to the performance dev tools. The condensed context really helps my brain learn this stuff too.
It’s a nice and short article, packed full of goodness.
