SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

gsap.utils offers a collection of pure helper functions for math, array handling, and value mapping used in GSAP animations.

Core Features & Use Cases

Clamp values to a range with gsap.utils.clamp, map ranges with gsap.utils.mapRange, and normalize inputs with gsap.utils.normalize.
Interpolate colors, numbers, and objects, generate random values, and snap values for grid-aligned animations, enabling concise and robust animation logic.
Use with ScrollTrigger, timelines, and callbacks to drive dynamic behaviors without mutating state.

Quick Start

Clamp a value to a 0–100 range using gsap.utils.clamp and apply it in a ScrollTrigger callback to normalize an input.

FAQPage Schema

How do I clamp or map values to a specific range in GSAP animations?▼

To clamp or map values in GSAP animations, use gsap.utils.clamp to restrict inputs and gsap.utils.mapRange to translate values from one range to another, enabling precise control over animation boundaries.

Can I interpolate colors and numbers without registering components in GSAP?▼

Yes, you can interpolate colors, numbers, and objects using gsap.utils without registration. The API is self-contained and provides pure helper functions that drive dynamic behaviors without mutating state.

What is the best way to normalize inputs for ScrollTrigger callbacks?▼

The best way to normalize inputs for ScrollTrigger callbacks is applying gsap.utils.normalize to transform values into a standard range, creating concise and robust scroll-based animation logic.

Does gsap.utils support snapping values for grid-aligned animations?▼

Yes, gsap.utils supports snapping values for grid-aligned animations. It provides pure helper functions that snap values to grids, ensuring elements align correctly during responsive animation sequences.

How do I generate random values for multiple targets in a GSAP timeline?▼

To generate random values for multiple targets in a GSAP timeline, use gsap.utils to generate random values. It supports both direct value usage and function forms for reuse across targets.

Why use gsap.utils for array handling instead of standard JavaScript methods?▼

Use gsap.utils for array handling because it offers pure helper functions specifically designed for math, array handling, and value mapping within GSAP animations, ensuring robust logic without state mutation.
