A tiny JavaScript library that computes cubic-bezier easing functions, matching CSS transition-timing-function behavior. It uses fast heuristics (dichotomic search, Newton-Raphson, sampling) for performance and precision.

Use cases

• create custom easing curves for JavaScript animations
• replicate CSS cubic-bezier timing functions in JS
• compute eased progress values between 0 and 1
• add ease-in ease-out curves to canvas or WebGL animations
• use consistent easing in React Native animations

When to choose

• you need CSS-compatible cubic-bezier easing in JavaScript
• you want a tiny, dependency-free, well-tested easing library
• you need high performance and precision for animation interpolation

When to avoid

• you only need CSS transitions and can use native CSS timing functions
• you need spring or physics-based animation easing
• you need a full animation framework with timelines and keyframes
