SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

gsap.utils provides a set of pure helper functions to perform common math, color parsing, normalization, and array operations inside GSAP-powered animations, reducing boilerplate and enabling a functional style.

Core Features & Use Cases

Clamp, mapRange, normalize: constrain, map, and normalize numeric inputs within animation flows.
Interpolate and random helpers: blend colors and values, generate controlled randomness in timelines.
Array and wrapping utilities: convert selectors, wrap values, and structure staggered animations with distribute-like helpers.
Use Case: simplify responsive UI motion by mapping scroll progress to animation progress without writing boilerplate math.

Quick Start

Use gsap.utils to perform common math and array operations inside your animation code.

FAQPage Schema

How do I map scroll progress to animation progress in GSAP without writing boilerplate math?▼

GSAP utility functions like mapRange and normalize map scroll progress to animation progress by constraining and normalizing numeric inputs. They act as pure helpers inside ScrollTrigger callbacks to simplify responsive UI motion.

Can I use gsap.utils to interpolate colors and values inside my animation code?▼

Yes, you can use gsap.utils interpolate and random helpers to blend colors and values inside animation code. These pure helpers generate controlled randomness in timelines and blend values within Tween vars and callbacks.

What is the best way to constrain numeric inputs in GSAP animation flows?▼

The best way to constrain numeric inputs in GSAP animation flows is using gsap.utils clamp. It acts as a pure helper function to constrain values, reducing boilerplate when writing mathematical transformations in animations.

Do I need to register a GSAP plugin to use utility functions like wrap and snap?▼

No, you do not need GSAP plugin registration to use utility functions like wrap and snap. The gsap.utils methods are exposed as pure helpers for array operations and value mapping without requiring plugin setup.

How do I convert selectors and structure staggered animations in GSAP?▼

Use gsap.utils toArray to convert selectors and wrapping utilities to structure staggered animations. These array utilities process values and structure animations with distribute-like helpers across web projects.
