SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

This skill simplifies complex animation logic by providing a suite of pure utility functions for mapping, clamping, snapping, and interpolating values, ensuring smooth and predictable motion.

Core Features & Use Cases

  • Value Transformation: Easily clamp, normalize, or map ranges (e.g., scroll progress to opacity) without manual math.
  • Collection Handling: Efficiently convert NodeLists to arrays and scope selectors to specific DOM containers.
  • Use Case: Use mapRange to convert a scroll position between 0 and 1000 into a rotation value between 0 and 360 degrees for a smooth parallax effect.

Quick Start

Use the gsap-utils skill to create a function that maps a scroll progress value from zero to one into a range of zero to three hundred sixty degrees.

FAQPage Schema
How do I map a scroll progress value to a rotation range in GSAP animations?

To map a scroll progress value to a rotation range in GSAP animations, use a math utility like mapRange to convert the scroll position into specific degree values, ensuring smooth and predictable motion without manual calculations.

What is the best way to normalize and clamp tween values for web animations?

Normalizing and clamping tween values for web animations involves using pure utility functions that restrict numbers within a defined range, ensuring consistent animation behavior and preventing unexpected visual glitches during sequence execution.

How do I convert NodeLists to arrays and scope DOM selectors for animation sequences?

To convert NodeLists to arrays and scope DOM selectors for animation sequences, use collection-handling utilities that efficiently isolate specific DOM containers, enabling functional programming patterns for targeted callback logic.

Does GSAP require manual math for interpolating values like opacity during scroll?

GSAP does not require manual math for interpolating values like opacity during scroll; utility functions handle value transformation and interpolation automatically, simplifying complex animation logic into predictable, functional patterns.

When should I use utility functions instead of manual math in frontend animation development?

Use utility functions instead of manual math in frontend animation development when you need precise value snapping, mapping, or interpolation to ensure smooth motion, preventing calculation errors that often cause visual glitches.
