Prefer Rekapi or GSAP

[joelburget]

I'd like to be told which to use because I have no prior knowledge to compare them on. Would be nice to have a note -- "If you don't know either Rekapi or GSAP, use Rekapi" (or GSAP).

Well, it depends...

• GSAP is much easier to configure. That's because rekapi has some additional configuration necessary (see spark-scroll-rekapi: lodash and underscore dependencies #3) beyond npm install spark-scroll-rekapi. If you're in the quick-and-dirty experimentation stage, use gsap to get up and running faster.
• Although I haven't done any benchmarks I suspect that rekapi is marginally faster than GSAP. That's because rekapi was built around the concept of timeline-based animation and spark-scroll is all about treating the scroll position as a timeline.
• GSAP supports animating SVGs. This is the main deciding factor for me. If I don't need SVG animation I prefer using rekapi although it's not a strong preference.
• Rekapi and GSAP have different licenses.
