vm2

The README for this repository is empty, so I can't provide a detailed explanation of what it does.

Based on the repo title and description alone: this project appears to be a sandbox tool for Node.js—a way to run JavaScript code in an isolated environment so it can't access or damage the rest of your system. Think of it like a locked room where untrusted code can execute safely. The name "vm2" suggests it may be a second version or improvement on an earlier sandbox tool.

To understand what this project actually offers, how to use it, or why you'd need it, you'd need to check the actual README file on the GitHub page or look at the code examples in the repository.
