Install node and npm

Node.js is a JavaScript runtime built on Chrome’s V8 JavaScript engine. Node.js uses an event-driven, non-blocking I/O model that makes it lightweight and efficient. Node.js’s package ecosystem, NPM, is the largest ecosystem of open source libraries in the world.

NPM is a package manager for JavaScript. Use NPM to install, share, and distribute code; manage dependencies in your projects; and share & receive feedback with others.
