The **`animVal`** read-only property of the SVGAnimatedBoolean interface represents the current animated value of the associated animatable boolean SVG attribute. If the attribute is not animated, animVal is the same as SVGAnimatedBoolean.baseVal.

### baseVal[](#baseval)

baseVal: boolean

The **`baseVal`** property of the SVGAnimatedBoolean interface is the value of the associated animatable boolean SVG attribute in its base (none-animated) state. It reflects the value of the associated animatable boolean attribute when no animations are applied.
