 <path id="line" d="M 0,30 h100" stroke="black" />
</svg>

<pre id="log"></pre>

#log {
 height: 70px;
 overflow: scroll;
 padding: 0.5rem;
 border: 1px solid black;
}

const logElement = document.querySelector("#log");
function log(text) {
 logElement.innerText = `${logElement.innerText}${text}\n`;
 logElement.scrollTop = logElement.scrollHeight;
}

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}`);
