In fact React has even let us port this idea to the third dimension with react-three-fiber; a wonderful library that uses three.js as a custom React render target.

In turn, it's common for us developers to lean on existing libraries to get the job done. framer-motion, react-spring and GSAP are great libraries, but we can learn a lot more about animation by implementing our own approach. What's more almost all animation libraries require us to work with someone else's conceptual model of user input. They provide extension APIs of course but we tend to implement each of these as closed-box concepts, you can consume them but not compose them freely.
What values? How much time? Those are up to the specific instance. Libraries like rxjs provide an algebra for working with streams, letting us mix them together, pluck out select elements and aggregate data over time. Others have explained streams far better than I can.
If you want to go deeper again then check out the project README and samsarajs. I'd like to try @most/core instead of rxjs here since it boasts impressive performance[ref]. To me, this seems like a promising area for further investigation. I've begun to experiment with a similar approach in Unity3d, hopefully more to report soon!
You know when you load a website and it has a bunch of fancy visualisations that respond to mouse and scroll position with animation? For most of the web's history creating experiences like these has either been impossible or required masochistic determination.

In ReactiveX terminology, this is a Subject wrapped up for easy consumption from React.
An interpolator acts as a translation layer between different numerical ranges. They typically take the form of functions accepting take a value, t, from 0...1 and output a value of t from 0...1. This might sound familiar if you've heard of easing functions, which are almost ubiquitous in programmatic animation:
