V8: The Engine Powering Chrome and Node.js
V8 is the engine that runs your JavaScript, translating it into machine code. It powers both the Chrome browser and the Node.js server-side runtime. The common footgun is confusing the engine (V8) with the runtime environment that provides it with APIs.
V8 is the high-performance engine that translates your JavaScript into machine code a computer can execute. It's the core of Google Chrome, running client-side code, and the heart of the Node.js runtime for servers. The main footgun is confusing the engine (V8) with the runtime (Node.js) or browser (Chrome). V8 only executes JS; the environment provides APIs for files, networking, or the DOM.
