An
SVGPointobject containing the coordinates of the point to be added when the list is initialized.
Return value
The added SVGPoint object.

Examples
The following example shows an SVG which contains a <polyline> with five coordinate pairs. Returning SVGPointList.length gives the value 5. After calling initialize(), returning SVGPointList.length gives the value 1.

points="50,0 21,90 98,35 2,35 79,90" />
</svg>
js
let example = document.getElementById("example");
console.log(example.points.length); //5;
let svgpoint = document.getElementById("svg").createSVGPoint();
