This feature is well established and works across many devices and browser versions. It’s been available across browsers since July 2015.
The value property of the SVGLength interface represents the floating point value of the <length> in user units.
Setting this attribute will cause SVGLength.valueInSpecifiedUnits and SVGLength.valueAsString to be updated automatically to reflect this setting.
The length value in user units as a float.
// Get an SVGLength object
const svg = document.querySelector("svg");
const length = svg.createSVGLength();
// Set the value
length.value = 10;
console.log(length.value); // Output: 10
// Reflecting the value
length.value = 20;
console.log(length.value); // Output: 20
