vm.isContext

vm.isContext

function to return false in order to get the

node:jsdom

node:jsdom

library to work: https://github.com/denoland/fresh/issues/427#issuecomment-1251918545

I am wondering how they did that.

I tried this:

import * as vm from "std/node/vm.ts";
vm.isContext = () => false;

import * as vm from "std/node/vm.ts";
vm.isContext = () => false;

But this throws the error:

error: TypeError: Cannot assign to read only property 'isContext' of object '[object Module]'

error: TypeError: Cannot assign to read only property 'isContext' of object '[object Module]'
