HostEnsureCanCompileStrings ( _calleeRealm_: a Realm Record, + optional _bodyText_: a String, + optional _direct_: a Boolean, ): either a normal completion containing ~unused~ or a throw completion

description
It allows host environments to block certain ECMAScript functions which allow developers to interpret and evaluate strings as ECMAScript code.
+

+ If _bodyText_ is present, or _direct_ signifying whether the evaluation is a direct eval, the host environment may base its decision on their values. +

The default implementation of HostEnsureCanCompileStrings is to return NormalCompletion(~unused~).
