Javenode is Java + V8 + Node.js. It is a Node.js simulator with Java in V8.

Javenode is an extension of `Javet `_ (Java + V8). It aims at simulating Node.js with Java in Javet V8 mode. Why? Because Javet V8 mode is much more secure than the Node.js mode, but lacks of some basic features, e.g. `setTimeout`, `setInterval`, etc. So, these **must-have** API can be found in Javenode.
