Built on Chrome’s V8 JavaScript engine, Node.js is a runtime environment that enables JavaScript to run outside the browser. This course will help you learn the fundamentals of Node.js to build portable applications.

You’ll learn about the components and build patterns of Node.js. You’ll also explore the API to learn how to create modules and write code to unique data files. Moreover, you’ll delve into the features and practices of JavaScript and build a REST API using the Express framework from scratch. This will set up authentication tokens with Passport.js and JSON web tokens, and finally build a live trivia game with Socket.IO.

By the end of this course, you’ll be equipped with the extensive knowledge to build rich and comprehensive Node.js applications running on the server with JavaScript.

Learn Node.js from Scratch

By the end of this lesson, we’ll be able to do the following:

- Use rest parameters to collect an arbitrary number of property keys in an object into a new object.
- Apply the spread operator to create a shallow copy of an object.

## Rest parameters and spread syntax with `...`

Depending on the context, the syntax `...` can be used as rest parameters or spread syntax. We can use rest and spread with arrays or objects.

### Rest parameters
