The lengthAdjust read-only property of the SVGTextContentElement interface reflects the lengthAdjust attribute of the given element. It takes one of the LENGTHADJUST_* constants defined on this interface.
lengthAdjust Property<svg width="200" height="100">
<text id="myText" x="10" y="50" textLength="100" lengthAdjust="spacing">
Hello, SVG!
</text>
</svg>
const textElement = document.getElementById("myText");
// Access the `lengthAdjust` property
const lengthAdjust = textElement.lengthAdjust;
// Log the base value of the `lengthAdjust` attribute
console.log(lengthAdjust.baseVal); // Output: 1 (e.g. LENGTHADJUST_SPACING)
