The createScriptURL() method of the TrustedTypePolicy interface creates a TrustedScriptURL object using a policy created by TrustedTypePolicyFactory.createPolicy().

args OptionalAdditional arguments to be passed to the function represented by TrustedTypePolicy.
A TrustedScriptURL object.
TypeErrorThrown if TrustedTypePolicy does not contain a function to run on the input.
In the below example a string containing the URL to an external resource is used as the input for createScriptURL(). The policy can check that this is an allowed URL before inserting it into an injection sink that could cause this external script to be executed.
const escaped = escapeURLPolicy.createScriptURL(
"https://example.com/my-script.js",
);
