{{APIRef("SVG")}}
The result read-only property of the {{domxref("SVGFEDisplacementMapElement")}} interface describes the assigned name of an SVG filter primitive as a {{domxref("SVGAnimatedString")}}.
It reflects the {{SVGElement("feDisplacementMap")}} element's {{SVGAttr("result")}} attribute. The attribute value is a {{cssxref("custom-ident")}}. If supplied, then graphics that result from processing this filter primitive can be referenced by an {{SVGAttr("in")}} attribute on a subsequent filter primitive within the same {{SVGElement("filter")}} element.
If no result attribute is defined, the filter's result.baseVal and result.animVal are empty strings, and the output of the <feDisplacementMap> filter will only be available for re-use as the implicit input into the next filter primitive if that filter primitive provides no value for its in attribute.
An {{domxref("SVGAnimatedString")}}.
const feDisplacementMapElement = document.querySelector("feDisplacementMap");
const filterName = feDisplacementMapElement.result;
console.log(filterName.baseVal); // the filter's assigned name
