Node node.js

Node.js in a runtime environment for JavaScript that runs serverside, allowing us to test, and build more complex applications in JavaScript – beyond the DOM.

It can be installed at nodejs.org, and has a range of applications which we won’t fully explore in this course.

It does however offer a simple alternative to running basic JavaScript on your computer without going through the browser.

Once you setup node on your local machine, you’ll be able to run JavaScript through the command-line.

Basic Example

Eg. Let’s say we’re prepping a basic script for the browser and we want to test the basic logic.

// a script without DOM interactions
// list.js
const list = ['Sam', 'Delilah', 'Mary'];

console.log(list.indexOf('Mary'));

node list.js
# output // 2

Cool.
