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 destructure objects, arrays, and function parameters.

## Destructuring

When we have to access numerous properties from an object, such as state or props in a React component, we can use destructuring assignment. This avoids assigning the properties to a variable one by one, resulting in cleaner syntax. We can destructure objects, arrays, and even function parameters.

### Destructuring objects

The destructuring syntax allows data to be easily extracted from arrays or objects into separate variables.

Take a look at the code below:
