SVGAnimatedLength: animVal property

Baseline Widely available

This feature is well established and works across many devices and browser versions. It’s been available across browsers since January 2020.

The animVal property of the SVGAnimatedLength interface contains the current value of an SVG enumeration. If there is no animation, it is the same value as the baseVal.
