{{APIRef("SVG")}}
The y read-only property of the {{domxref("SVGSVGElement")}} interface describes the vertical coordinate of the position of that SVG as an {{domxref("SVGAnimatedLength")}}. When an {{SVGElement("svg")}} is nested within another <svg>, the vertical coordinate is a length in the user coordinate system that is the given distance from the origin of the user coordinate system along the y-axis. Its syntax is the same as that for <length>.
It reflects the {{SVGElement("svg")}} element's {{SVGAttr("y")}} geometric attribute. The default value is 0. The y attribute has no effect on outermost <svg> elements; only on nested ones. The CSS {{cssxref("y")}} property takes precedence over the <svg> element's y attribute, so the value may not reflect the element's appearance.
An {{domxref("SVGAnimatedLength")}}.
const svg = document.querySelector("svg");
const topPosition = svg.y;
console.dir(leftPosition.baseVal.value); // the `y` value
