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 TrustedScript interface of the Trusted Types API represents a string with an uncompiled script body that a developer can insert into an injection sink that might execute the script. These objects are created via TrustedTypePolicy.createScript() and therefore have no constructor.

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