I've tried my best searching in algolia to find it, but to no luck.
It was a site posted here that let you compare various common actions and methods across the different JS UI frameworks (Vue3, Vue2, React, Svelte).
I believe it was posted sometime within the past 3-4 months, but I also use the past feature a lot so I can't guarantee it.
I thought it was really cool, but I didn't bookmark it, and I've recently found myself needing it.
Any help is appreciated, thank you!
