/Web APIs


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.
