Getting the total length of a <path>

In this example, we get the total length of two paths: a basic line and a heart shape.

html
<svg width="200" height="100">
  <path
    id="heart"
    fill="red"
    d="M 10,30
           A 20,20 0,0,1 50,30
           A 20,20 0,0,1 90,30
           Q 90,60 50,90
           Q 10,60 10,30 z" />
  <path id="line" d="M 0,30 h100" stroke="black" />
</svg>
js
const complexPath = document.getElementById("heart");
const basicPath = document.getElementById("line");

// Access the pathLength property
const complexPathLength = complexPath.getTotalLength();
const basicPathLength = basicPath.getTotalLength();

// The base value of the pathLength attribute
log(`complexPathLength: ${complexPathLength}`);
log(`basicPathLength: ${basicPathLength}`);
