What Is Node.js?
what is Chrome’s V8 JavaScript Engine?
Node.js® is a JavaScript runtime built on Chrome’s V8 JavaScript engine. Node.js is an event-based, non-blocking, asynchronous I/O runtime that uses Google’s V8 JavaScript engine and libuv library.
The V8 engine is the open-source JavaScript engine that runs in Google Chrome and other Chromium-based web browsers, including Brave, Opera, and Vivaldi. It was designed with performance in mind and is responsible for compiling JavaScript directly to native machine code that your computer can execute.
What does it mean that node is a JavaScript runtime?
when we say that Node is built on the V8 engine, we don’t mean that Node programs are executed in a browser. They aren’t. Rather, the creator of Node (Ryan Dahl) took the V8 engine and enhanced it with various features, such as a file system API, an HTTP library, and a number of operating system–related utility methods.
- This means that Node.js is a program we can use to execute JavaScript on our computers. In other words, it’s a JavaScript runtime.
