A series of lessons to help you get more familiar with modern JavaScript syntax.

JavaScript® (often shortened to JS) is a lightweight, interpreted, object-oriented language with first-class functions, most known as the scripting language for Web pages, but used in many non-browser environments as well such as node.js or Apache CouchDB. It is a prototype-based, multi-paradigm scripting language that is dynamic, and supports object-oriented, imperative, and functional programming styles.

Learn how to build a simple REST API to store notes using the latest built-in node features including native ES modules, the fs/promises API, async/await, the nullish coalescing operator, and destructuring. No compilers, no build steps, pure code.

This collection of lessons is great for beginners to Express as long as they are familiar with JavaScript and the HTTP protocol. Those more familiar with node and express will appreciate a fast-paced, modern take on using these popular tools and will likely benefit most from the lessons on input validation, models (which emphasizes a lot of new syntax), using fs/promises to serialize a `Map`, and accessing asynchronous data with `async/await`.

Pre-requisites:

- [Install curl](https://curl.haxx.se/)
- [Install node 14](http://nodejs.org/)
- Be familiar with the terminal

View the source for this project in the [project's github repo](https://github.com/xjamundx/egghead-express).

**Notes**:

- I'm not very pedantic about REST and basically just mean an API over HTTP
- [Express 5](https://expressjs.com/en/guide/migrating-5.html) is still in alpha (and has been for over two years), but most of these lessons apply to Express 4 as long you use something like [express-async-errors](https://www.npmjs.com/package/express-async-errors) to add support for `async` routes and middleware

Express is a minimal and flexible Node.js web application framework that provides a robust set of features for web and mobile applications.

Listening to and responding to events is a foundational skill for building software for the web. The Document Object Model, or DOM for short, has a powerful built-in event system. And yet, many of us have a pretty basic understanding of the DOM event system and only scratch the surface of the available power. 

This lack of understanding leads to bugs in our applications and writing lots of code to work around the DOM event system rather than leveraging it. The goal of the course is that you will walk away with the confidence to successfully and meaningfully engage with the DOM event system.

The DOM event visualizer [domevents.dev](https://domevents.dev) will be used to explain many behaviors throughout the course. You are welcome to play with the visualizer yourself to continue your learning

  Vue is a progressive framework for building UIs that allows you to incrementally integrate the technology into any existing project that you're working on. This makes it a great tool for you to learn as you can bring it anywhere.

This course is for learners just starting out in web development as well as for those who want to get up to speed on Vue 3 as fast as possible. You'll learn all the foundational skills of web development and how they are presented in Vue. 

We will start with an HTML, CSS, and JavaScript file as to not distract you with any possible tooling that goes on top of the building websites with Vue. 

You will incrementally build an app that sells comedy event tickets. In the end, you'll see how to deploy the application with Netlify Drag and Drop.

Vue (pronounced /vjuː/, like view) is a progressive framework for building user interfaces. Unlike other monolithic frameworks, Vue is designed from the ground up to be incrementally adoptable. The core library is focused on the view layer only, and is very easy to pick up and integrate with other libraries or existing projects. On the other hand, Vue is also perfectly capable of powering sophisticated Single-Page Applications when used in combination with modern tooling and supporting libraries.

JavaScript is full of inconsistent APIs. Wrapping those APIs in functions allows you to have full control over how to configure them and make them more reusable.

This becomes even more beneficial when dealing with the async nature of JavaScript. You'll learn how a broadcaster is a function that wraps another function (which we call listeners) and modifies the behavior. We will build up this pattern in a way that allows you to compose broadcasters together making your code more reusable.

Establish Callback and Closure patterns Around Async Browser Behaviors

In the previous section, [07 Building Light Search Box](https://egghead.io/playlists/building-light-search-box-bb64), we implemented a search box with the pattern that we've built in this course. This works great but doesn't have as much business logic applied as other async scenarios.

In this section, we will implement a word game where the values coming in from the user will be piped to different listeners to be consumed. Along the way, complex business logic will be applied to determine if the user won the game or not.

**You're in Section 08, the last of [Composing Closures and Callbacks in JavaScript](https://egghead.io/playlists/composing-closures-and-callbacks-in-javascript-1223)**

Implementing a Word Game with Patterns and React

As developers, we have a responsibility to protect the data our users trust us with. No one wants to wake up to the news that their site was hacked and all of the user accounts stolen.

Security is important, yet it is often overlooked and forgotten.

Part of the reason for this is that security seems hard to get right. This results in developers crossing their fingers and hoping for the best.

In this course, you'll learn how to protect your application by learning how to attack it.

Web Security Essentials: MITM, CSRF, and XSS

The concept of 'done-ness' is not something that is often considered when writing functions in JavaScript — you end up just running out of data or a function stops getting called.

There are many async scenarios that make sense to signal that work is completed. 

By following a completion pattern, we can easily trigger repetition and sequencing (async or not) into our code.

**You're in Section 05 of [Composing Closures and Callbacks in JavaScript](https://egghead.io/playlists/composing-closures-and-callbacks-in-javascript-1223)**

Use a Completion Pattern to enable Repetition and Sequencing

Now that you've been introduced to the pattern in-depth, let's implement it in a few common Async Scenarios.

You'll notice the benefits of re-using broadcasters through different scenarios as well as tweaking behavior through operators like when to start and stop code.

**You're in Section 04 of [Composing Closures and Callbacks in JavaScript](https://egghead.io/playlists/composing-closures-and-callbacks-in-javascript-1223)**

Implement the Pattern in Common Async Scenarios

In this section, we will introduce another concept to the pattern that we've created: 

**Operators**.

Operators are the final big piece that allows us to bend all asynchronous behaviors to our will. They give us a chance to redefine broadcasters and listeners in any way we want. 

We'll several operators throughout this section to implement mapping, filtering, and piping behaviors (and more!).

By the end, you'll get a real sense of how you can continue building on top of the functionality you've already built.

Using immutable data structures provides many benefits, including making your code easier to reason about and less prone to bugs.

However, since JavaScript doesn't include support for immutable data structures out of the box, you need to use a third party library. But which one to choose?

In this self-paced workshop, Immer's creator Michel Westrate will guide you through the creation of a multi-user Gift Tracking app.

You'll learn the basics of using Immer to handle immutable state updates, then go further into change distribution and implementing an undo/redo.

After this workshop, you'll be ready to leverage immutable data structures in your own applications!

React is one of the web’s most popular frameworks for building JavaScript applications. 

If you know what you’re doing, React can drastically simplify how you build, use, and maintain code.

Whether you’re a React newbie or you’re ready for advanced techniques, you can level-up with egghead. Explore our in-depth courses, lessons, and community resources to build more powerful applications and crack open your career.

Immutable JavaScript Data Structures with Immer

Before we dive deep into the pattern of composing callbacks and closures, we need to take start with the definitions and basic building blocks that we will be using for the rest of the course. 

You'll be able to answer questions like:

- What is a Closure?
- What is a Callback?
- Why does Callback Hell happen and how can we handle it?

We will see that by establishing a contract between functions and holding to the pattern that is established, you will have gained a lot of power and flexibility in writing reusable, robust functions.

**You're in Section 01 of [Composing Closures and Callbacks in JavaScript](https://egghead.io/playlists/composing-closures-and-callbacks-in-javascript-1223).**

Introduction to Callbacks, Broadcasters, and Listeners

It all starts with syntax. From there, once you’ve got the concepts down, you can move into using a framework where you figure out how to make things “just work”.

Everything is great, until it’s not.

If someone put you on the spot right now and asked you to explain `this`, would they like your answer?

What about prototypal inheritance or coercion?

In this workshop, you’ll be taking things to the next level, shining a light into “black-box” concepts like prototypes, the `this` keyword, and what primitive types are.

Tyler will walk you through each concept, and build your understanding through examples in the areas you need to know.

Advanced JavaScript Foundations

Ever built a website? Did it have more than one page?

If it did, you learned quickly how essential routing is to the success of your project. And in so many frameworks routing is a painful and complex thing to learn.

But not in Vue!

Vue has an incredibly clean and powerful library called vue-router that takes care of everything you could need.

In this course, we'll cover what you need to know to get started with vue-router.
