Limited availability

This feature is not Baseline because it does not work in some of the most widely-used browsers.

Note: This feature is available in Web Workers.

The TrustedScriptURL interface of the Trusted Types API represents a string that a developer can insert into an injection sink that will parse it as a URL of an external script. These objects are created via TrustedTypePolicy.createScriptURL() and therefore have no constructor.

The value of a TrustedScriptURL object is set when the object is created and cannot be changed by JavaScript as there is no setter exposed.
