Official GSAP skill for gsap.utils — clamp, mapRange, normalize, interpolate, random, snap, toArray, wrap, pipe. Use when the user asks about gsap.utils,…
gsap.utils When to Use This Skill Apply when writing or reviewing code that uses gsap.utils for math, array/collection handling, unit parsing, or value mapping in animations (e.g. mapping scroll to a value, randomizing, snapping to a grid, or normalizing inputs). Related skills: Use with gsap-core, gsap-timeline, and gsap-scrolltrigger when building animations; CustomEase and other easing utilities are in gsap-plugins. Overview gsap.utils provides pure helpers; no need to register. Use in tween vars (e.g. function-based values), in ScrollTrigger or Observer callbacks, or in any JS that drives GSAP. All are on gsap.utils (e.g. gsap.utils.clamp()). Omitting the value: function form. Many utils accept the value to transform as the last argument. If you omit that argument, the util returns a function that accepts the value later. Use the function form when you need to clamp, map, normalize, or snap many values with the same config (e.g. in a mousemove handler or tween callback). Exception: random() — pass true as the last argument to get a reusable function (do not omit the value); see random(). // With value: returns the result gsap.utils.clamp(0, 100, 150); // 100
