SHOCKER! The CSS cubic-bezier easing functions found in the top google search results are off, and sometimes way off, compared to @robpenner's orignal code. Use these instead 👇gist.github.com/patrickmatte/e… @sitnikcode

@patmat @sitnikcode Check out this research paper which analyzes errors in approximations of my easing functions and aims to improve: researchgate.net/profile/Darius…

@robpenner @sitnikcode IBM has two css easing methods in their branding guidelines, expressive: cubic-bezier(0.4, 0.14, 0.3, 1) and productive: cubic-bezier(0.2, 0, 0.38, 0.9). I wrote a cubic bezier API in JS to be able to use those exact numbers.

@robpenner @sitnikcode That's how I was able to countercheck easings.net numbers with the ones from your code.

@patmat @robpenner Thanks for noticing it. Do your want to send PR to save your name in this project’s history? github.com/ai/easings.net…

@sitnikcode @robpenner Sure thing, you can expect a PR later today. 👍
