Node is powered by the JavaScript engine used in Google Chrome, called V81. In this post I'm going to guide you through two steps: making a "Hello World" example in V8 making a crude Node runtime with support for 3 statements: console.log, console.error and quit for quitting the process In our new crude runtime we'll execute the following script: console.log("🎉"); b=4+4; console.error(b); quit();
