SVGTransformList: initialize() method

initialize(newItem)

</svg>

const svgElement = document.querySelector("svg");

// Apply an initial translate transformation to the <rect> element
const translateTransform = svgElement.createSVGTransform();
translateTransform.setTranslate(50, 50);
transformList.appendItem(translateTransform);
// Number of transformations before initialization
console.log(

); // Output: 1
// Create a new scale transformation
const scaleTransform = svgElement.createSVGTransform();
scaleTransform.setScale(2, 2);
// Initialize the list with the new scale transform
transformList.initialize(scaleTransform);
// Number of transformations after initialization
console.log(
