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.

TrustedScript.toJSON()

Returns a JSON representation of the stored data.

TrustedScript.toString()

A string containing the sanitized script.

The constant sanitized is an object created via a Trusted Types policy.

const sanitized = scriptPolicy.createScript("eval('2 + 2')");
console.log(sanitized); /* a TrustedScript object */
