Function: spring()

function spring(__namedParameters?): (t) => number;

Returns a spring-physics easing function configured with stiffness and damping. The returned function maps a time value t (0–1) to a spring-interpolated position.

Parameters

Parameter	Type
__namedParameters	{ damping?: number; stiffness?: number; }
__namedParameters.damping?	number
__namedParameters.stiffness?	number

Returns

(t) => number

Example

const ease = spring({ stiffness: 120, damping: 14 })
ease(0.5) // ~0.984
