The
Function()constructor can execute its arguments as JavaScript.Similarly
eval()executes its input as JavaScript.This updates the TrustedType information for both methods.
Note, I provided an example for
eval()but notFunction. I wasn't sure if I should do either, because even though this is notionally safer than not using trusted types, there is really no direction on how you can practically and generically transform a script so that it is safe.For the
eval()case I just indicated the use of custom transforming function, for which I provided no implementation. For Function, I added a disclaimer and linked to the eval() example.Related docs work tracked in #41507
