Hi, I’m Sandro

JavaScript has come a long way since I knew it as the “D” in DHTML. For anyone like me, who’s been reluctant to use the latest syntax that could require polyfills or a transpiler, I’ve written this cheatsheet to get you caught up on all the goodness that’s widely supported in modern browsers.

If you want to support the pinch-to-zoom gesture, and two-finger panning while using a trackpad on a webpage, you only need to check for one special property on the wheel event.
