/**
 * The `node:vm` module enables compiling and running code within V8 Virtual
 * Machine contexts.
 *
 * **The `node:vm` module is not a security**
 * **mechanism. Do not use it to run untrusted code.**
 *
 * JavaScript code can be compiled and run immediately or
 * compiled, saved, and run later.
 *
 * A common use case is to run the code in a different V8 Context. This means
 * invoked code has a different global object than the invoking code.
 *
 * One can provide the context by `contextifying` an
 * object. The invoked code treats any property in the context like a
 * global variable. Any changes to global variables caused by the invoked
 * code are reflected in the context object.
 *
 * ```js
 * import vm from 'node:vm';
 *
 * const x = 1;
 *
 * const context = { x: 2 };
 * vm.createContext(context); // Contextify the object.
 *
 * const code = 'x += 40; var y = 17;';
 * // `x` and `y` are global variables in the context.
 * // Initially, x has the value 2 because that is the value of context.x.
 * vm.runInContext(code, context);
 *
 * console.log(context.x); // 42
 * console.log(context.y); // 17
 *
 * console.log(x); // 1; y is not defined.
 * ```

     * [`eval()`](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/eval) _does_ have access to the
     * local scope, so the value `localVar` is changed. In this way `vm.runInThisContext()` is much like an [indirect `eval()` call](https://es5.github.io/#x10.4.2), e.g.`(0,eval)('code')`.
     *
     * ## Example: Running an HTTP server within a VM
     *
     * When using either `script.runInThisContext()` or {@link runInThisContext}, the code is executed within the current V8 global

     *
     * In order to run a simple web server using the `node:http` module the code passed
     * to the context must either import `node:http` on its own, or have a
     * reference to the `node:http` module passed to it. For instance:
     *
     * ```js
     * 'use strict';
     * import vm from 'node:vm';
     *
     * const code = `
     * ((require) => {
     * const http = require('node:http');
     *
     *   http.createServer((request, response) => {
     *     response.writeHead(200, { 'Content-Type': 'text/plain' });
     *     response.end('Hello World\\n');

     *   console.log('Server running at http://127.0.0.1:8124/');
     * })`;
     *
     * vm.runInThisContext(code)(require);
     * ```
     *
     * The `require()` in the above case shares the state with the context it is
     * passed from. This may introduce risks when untrusted code is executed, e.g.
     * altering objects in the context in unwanted ways.

     * The `vm.Module` class provides a low-level interface for using
     * ECMAScript modules in VM contexts. It is the counterpart of the `vm.Script`
     * class that closely mirrors [Module Record](https://tc39.es/ecma262/#sec-abstract-module-records)s as defined in the ECMAScript
     * specification.
     *
     * Unlike `vm.Script` however, every `vm.Module` object is bound to a context from
     * its creation.
     *
     * Using a `vm.Module` object requires three distinct steps: creation/parsing,
     * linking, and evaluation. These three steps are illustrated in the following
     * example.
     *
     * This implementation lies at a lower level than the `ECMAScript Module
     * loader`. There is also no way to interact with the Loader yet, though
     * support is planned.
     *
     * ```js
     * import vm from 'node:vm';
     *
     * const contextifiedObject = vm.createContext({
     *   secret: 42,
     *   print: console.log,
     * });
     *
     * // Step 1
     * //
     * // Create a Module by constructing a new `vm.SourceTextModule` object. This
     * // parses the provided source text, throwing a `SyntaxError` if anything goes
     * // wrong. By default, a Module is created in the top context. But here, we
     * // specify `contextifiedObject` as the context this Module belongs to.
     * //
     * // Here, we attempt to obtain the default export from the module "foo", and
     * // put it into local binding "secret".
     *
     * const rootModule = new vm.SourceTextModule(`
     *   import s from 'foo';
     *   s;
     *   print(s);
     * `, { context: contextifiedObject });
     *
     * // Step 2
     * //
     * // "Link" the imported dependencies of this Module to it.
     * //
     * // Obtain the requested dependencies of a SourceTextModule by
     * // `sourceTextModule.moduleRequests` and resolve them.
     * //
     * // Even top-level Modules without dependencies must be explicitly linked. The
     * // array passed to `sourceTextModule.linkRequests(modules)` can be
     * // empty, however.
     * //
     * // Note: This is a contrived example in that the resolveAndLinkDependencies
     * // creates a new "foo" module every time it is called. In a full-fledged
     * // module system, a cache would probably be used to avoid duplicated modules.
