Last Updated : 30 Mar, 2022

The SVG SpecularLighting.specularExponent property returns the SVGAnimatedNumber object corresponding to the specularExponent component of the SpecularLighting.specularExponent element.

Syntax:

var a = FESpecularLighting.specularExponent

Return value: This property returns the SVGAnimatedNumber object corresponding to the specularExponent component of the SpecularLighting.specularExponent element.
