The x read-only property of the SVGFEPointLightElement interface describes the horizontal coordinate of the position of an SVG filter primitive as a SVGAnimatedNumber.
It reflects the x attribute of the <fePointLight> element, which can be used to define the light source in a point light effect. The attribute is a <number>. The default value is 0.
const fePointLight = document.querySelector("fePointLight");
const leftPosition = fePointLight.x;
console.log(leftPosition.baseVal.value); // the `x` value
