The valueAsString property of the SVGAngle interface represents the angle's value as a string, in the units expressed by unitType.
Setting this attribute will cause value, valueInSpecifiedUnits, and unitType to be updated automatically to reflect this setting.
A string; the value of the angle.
valueAsString// Get an SVGAngle object
const svg = document.querySelector("svg");
const angle = svg.createSVGAngle();
// Set the value using valueAsString in degrees
angle.valueAsString = "45deg";
console.log(angle.valueAsString); // Output: "45deg"
console.log(angle.value); // Output: 45 (in degrees)
// Set the value using valueAsString in radians
angle.valueAsString = "1.57rad";
console.log(angle.valueAsString); // Output: "1.57rad"
console.log(Math.round(angle.value)); // Output: 90 (since 1.57 radians is approximately 90 degrees)
