The animVal read-only property of the SVGAnimatedTransformList interface represents the animated value of the transform attribute of an SVG element.
This property reflects the SVG element's transform, the <linearGradient> or <radialGradient> element's gradientTransform attribute, or the <pattern> element's patternTransform attribute as a readonly SVGTransformList, providing access to the dynamically updated SVGTransform for each transform function during an animation. If no animation is active, this property will return the same value as baseVal.
An SVGTransformList object that reflects the current animated value of the transform attribute.
// Get the rectangle element
const rect = document.querySelector("rect");
// Access the animated transform list (if any)
const animTransforms = rect.transform.animVal;
// Log the animated transforms to the console
console.dir(animTransforms);
