Framer doesn't spit out React code once you're done. Code used in prototyping is hugely different and unusable in production. And Framer makers know this and openly talk about this, they're not trying to be a code generator.
Well, I've found it pretty useful to hand animation in js as-is for specific patterns (as we actually handle the specific bezier curve animation, timings, etc...)
Sure you may not use the components wholesale but you can still pick out specific parts, such as full CSS code or bezier curves as the sibling poster put it.
