I've been making an app with React Native and react-native-svg and even though react-native-svg supports transformations, I've had to do a lot of transforms with trigonometry (i.e. rotating a shape around a center point, then getting the new bounding box, which requires things such as Math.atan2).
It's made me really appreciate 1. how much easier front end web development is and 2. how far we've gotten. I cannot tell you how much I appreciate web methods like getBoundingClientRect() or element.closest(), and how easy it is to make animations with CSS and move things around with transforms.
