What are the use cases for the Node.js vm core module?

The Node.js "vm" core module is primarily used for executing JavaScript code within a separate V8 Virtual Machine context, effectively isolating the executed code from the main application's global context. This isolation helps in several scenarios:

1. Running Untrusted Code: One of the most common use cases for the "vm" module is to safely execute untrusted code. This is particularly useful in applications that need to run code provided by users or external sources without risking the integrity or security of the main application[1][5].

2. Testing and Debugging: Developers can use the "vm" module to test new code or debug existing code in an isolated environment. This prevents the test code from affecting the application's state or the global environment[1].

3. Sandboxing for Security: Although the "vm" module is not a security mechanism on its own and should not be relied upon to provide complete security isolation, it can be part of a larger security strategy. It provides a basic level of isolation that can be enhanced with additional security layers[5].

4. Custom Script Execution in Applications: Applications like interactive learning platforms or coding challenge websites might use the "vm" module to execute user-generated scripts. This allows users to write and test code directly within the platform in a controlled manner[1][2].

5. Server-Side Computation: For applications that require executing dynamically gen...
