The clear() method of the SVGPointList interface removes all items from the list.

None.

None (undefined).

NoModificationAllowedError DOMException

Thrown if the list is read-only.

The following example shows an SVG which contains a <polyline> with five coordinate pairs. Calling clear() empties the list. Therefore the polyline no longer displays in the SVG.

<svg id="svg" viewBox="-10 -10 120 120" xmlns="http://www.w3.org/2000/svg">
  <polyline
    id="example"
    stroke="black"
    fill="none"
    points="50,0 21,90 98,35 2,35 79,90" />
</svg>

let example = document.getElementById("example");
example.points.clear();
