gsap-utils
Pure utility functions for math, value mapping, randomization, array handling, and unit parsing in GSAP animations.
What it does
- ✅ Use snap for grid-aligned or step-based values; use toArray when GSAP or your code needs a real array from a selector or NodeList.
- ✅ Use gsap.utils.selector(scope) in components so selectors are scoped to a container or ref.
- ❌ Assume mapRange / normalize handle units; they work on numbers. Use getUnit / unitize when units matter.
- ❌ Override or rely on undocumented behavior; stick to the documented API.
Requirements & configuration
- ✅ Use snap for grid-aligned or step-based values; use toArray when GSAP or your code needs a real array from a selector or NodeList.
