Under the hood, Electron is powered by the Chromium rendering engine and Node.js. Chromium is the open-source part of Google’s Chrome browser. And Node.js is powered by V8, which is Chrome’s JavaScript engine. So, to clarify: I’m running a laptop that has an operating system called “Chrome OS,” which is mostly just Google’s Chrome browser and a little bit of Linux, and now I’m installing “real” Linux applications inside a virtual machine on top of Chrome OS, and most of those applications are built entirely with Chrome-derived technologies.
