SVGNumberList

Baseline Widely available

This feature is well established and works across many devices and browser versions. It’s been available across browsers since January 2020.

The SVGNumberList interface defines a list of numbers.

An SVGNumberList object can be designated as read only, which means that attempts to modify the object will result in an exception being thrown.

An SVGNumberList object is indexable and can be accessed like an array.
