  <rect
    width="100"
    height="100"
    fill="blue"
    transform="translate(50,50) rotate(45)" />
</svg>
js
const svgElement = document.querySelector("svg");
const rectElement = svgElement.querySelector("rect");

// Access the transform list of the <rect> element
const transformList = rectElement.transform.baseVal;

const removedTransform = transformList.removeItem(0);

console.log(`Updated number of transformations: ${transformList.length}`); // Output: 1
