{{APIRef("SVG")}}
The baseVal read-only property of the {{domxref("SVGAnimatedAngle")}} interface represents the base (non-animated) value of the associated <angle> on an SVG element. This property is used to retrieve the static value of the <angle>, unaffected by any ongoing animations.
This property reflects the <angle> value of the {{SVGattr("orient")}} attribute of the SVG {{SVGElement("marker")}} element, which is the same as the {{domxref("SVGMarkerElement.orientAngle")}} property.
An {{domxref("SVGAngle")}} object representing the base value of the <angle> content type.
const marker = document.querySelector("[orient]");
// Set the orient attribute with an angle
marker.setAttribute("orient", "90");
const baseAngle = marker.orientAngle.baseVal; // an SVGAngle object
console.log(baseAngle.value); // Output: 90
console.log(baseAngle.unitType); // Output: 1 (constant for SVG_ANGLETYPE_UNSPECIFIED)
