variable constants.DONT_CONTEXTIFY

This constant, when used as the contextObject argument in vm APIs, instructs Node.js to create a context without wrapping its global object with another object in a Node.js-specific manner. As a result, the globalThis value inside the new context would behave more closely to an ordinary one.

When vm.constants.DONT_CONTEXTIFY is used as the contextObject argument to createContext, the returned object is a proxy-like object to the global object in the newly created context with fewer Node.js-specific quirks. It is reference equal to the globalThis value in the new context, can be modified from outside the context, and can be used to access built-ins in the new context directly.
