Description of the problem
See following test case:
const vm = require('node:vm');
const context = vm.createContext({ foo: console.log });
(async () => {
const module = new vm.SourceTextModule(
'foo( console ); console.log( "bar" );',
{ context: context, });
await module.link(() => {});
await module.evaluate();
})();From basic understand as document in the API this should fail, as the "console" has never been handed down into the new context.. yet it is there. Albeit the log is not working.
I guess this is a documentation issue, as the standard javascript globals are created regardless? If I hand down the console object into the created context, console.log works, but if not IMO it should either throw a call to undefined function error, or as said, the docs should describe better what is actually happening on creating a new Context.
PS: I'm aware that nodes vm.SourceTextModule probably may not be properly sandboxed, in my case this doesn't matter, I just found it confusing, the "console" object exists at all in the new context.
