The setSkewY() method of the SVGTransform interface sets the transform type to SVG_TRANSFORM_SKEWY, with parameter angle defining the amount of skew along the Y-axis.
setSkewY(angle)angleA float defining the amount of skew in degrees.
None (undefined).
NoModificationAllowedError DOMExceptionThrown if the attribute or the SVGTransform object is read-only.
// Select an SVG element and create a transform object
const svgElement = document.querySelector("svg");
const transform = svgElement.createSVGTransform();
// Apply a skew of 30 degrees along the Y-axis
transform.setSkewY(30);
// Log the applied transformation angle
console.log(`Skew Angle: ${transform.angle}`); // Output: 30
