SVGScriptElement: async property

Baseline 2025
Newly available

Since December 2025, this feature works across the latest devices and browser versions. This feature might not work in older devices or browsers.

The async property of the SVGScriptElement interface is a boolean value that controls how the script should be executed. For classic scripts, if the async property is set to true, the external script will be fetched in parallel to parsing and evaluated as soon as it is available. For module scripts, if the async property is set to true, the script and all its dependencies will be fetched in parallel to parsing and evaluated as soon as they are available.

It reflects the async attribute of the <script> element.

Value

A boolean.

Examples
