The result read-only property of the SVGFEComponentTransferElement interface describes the assigned name of an SVG filter primitive as a SVGAnimatedString.
It reflects the <feComponentTransfer> element's result attribute. The attribute value is a <custom-ident>. If supplied, then graphics that result from processing this filter primitive can be referenced by an in attribute on a subsequent filter primitive within the same <filter> element.
If no result attribute is defined, the filter's result.baseVal and result.animVal are empty strings, and the output of the <feComponentTransfer> 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.
const feComponentTransferElement = document.querySelector(
"feComponentTransfer",
);
const filterName = feComponentTransferElement.result;
console.log(filterName.baseVal); // the filter's assigned nameSVGFEComponentTransferElement.in1<feFuncR>, <feFuncG>, <feFuncB>, <feFuncA> elements<custom-ident> data type
