Official GSAP utility functions for math operations, value mapping, and array manipulation in animations. Covers clamp, mapRange, normalize, interpolate, random, snap, distribute, and other gsap.utils helpers with their function-form patterns (omit the last parameter to get a reusable function). Essential when you're mapping scroll position to animation values, randomizing properties across multiple elements, snapping to grids, or distributing values with custom easing. The distribute function alone saves tons of boilerplate for complex staggers. Works seamlessly with ScrollTrigger callbacks and function-based tween values where you need consistent mathematical transformations.
