Experience

React Addressable Sliders

https://github.com/giovanni-caiazzo/react-addressable-sliders
I developed this React-based project that lets users create multiple sliders and address them with objects instead of arrays. This feature allows having total control of each slider and interactions between them. I have recently updated it in TypeScript.
