Learn Angular, Javascript and Rust

On the surface, starting a project sounds easy. First you make some directories, install some dependencies, then you write some code.

But there's a bit more to it than just those three steps.

The type of project you're working on impacts the decisions you make. It gets more complicated when you're working on multiple projects that are related. For example, maybe you have a customer-facing frontend app, an admin dashboard app, and a single backend used for both.

How does this change your directory structures? How should you share code between projects? What happens when you add a Design System into the mix?

It can get hard to keep things straight in your head.

Nx is a tool that aims to solve these problems for you, whether you're working solo on a small full-stack app or on a dev team of thousands.

It's not just an opinionated folder structure. When you create an app with Nx, it generates unit and e2e test setups as well as preparing bundling and code-splitting with Webpack, and stubbing out common features like routing.

One of the coolest features of Nx is its Dependency Graph. The graph can visually show you the relationship between the parts of your application, and is optimized to ensure that compiling, testing, and linting only happens in the affected areas of your project.

In this course, Juri Strumpflohner demonstrates these features and more through the iterative creation of a React + Storybook + Express app. Don't worry if this isn't your preferred stack! Nx supports the most popular frameworks & libraries on the web.

More importantly, the focus of this course is more on the workflow than the implementation.

Watch Juri's course, and see if the Nx tooling & workflow is right for you and your team!

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.

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

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.

In this course, Chris takes a README-driven approach to build out a Rust CLI that supports content authoring for a digital garden.

Specifically, you'll work through the first command for the CLI, writing files. You start by initializing a new Cargo binary crate through creating the `write` command that allows you to create files (and their contents) to the folder that you set. 

Step by step you'll learn about:
- Handling user input
- Error handling
- Rust Move semantics
- Rust Copy semantics
- Integration testing

...and more!

Rust is a systems programming language that runs blazingly fast, prevents segfaults, and guarantees thread safety.

ES6 and Beyond

Optional chaining ?. in javascript is a new feature introduced in ES2020. Optional chaining changes the way properties are accessed from deeply nested objects. It fixes the problem of having to do multiple null checks when accessing long chain of object properties in javascript.

Optional Chaining

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.

**You're in Section 02 of [Composing Closures and Callbacks in JavaScript](https://egghead.io/playlists/composing-closures-and-callbacks-in-javascript-1223)**

Establish Callback and Closure patterns Around Async Browser Behaviors

When merging two objects in javascript, you can _shallow_ merge them, or _deep_ merge them.  These videos show how to do both, and talk about the pros and cons of each approach. 

Merge Objects in JavaScript

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

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.

**You're in Section 03 of [Composing Closures and Callbacks in JavaScript](https://egghead.io/playlists/composing-closures-and-callbacks-in-javascript-1223)**

Use the Callback and Closure Pattern to Build Advanced Async Behaviors

The difficulty of managing state is one of the primary reasons our applications become so complex. We try and manage this complexity with a lot of booleans, somewhat semantic variables like `isLoading`, `wasFetched`, and `hasError`, and over-engineered systems that are _still_ full of bugs. Surely, there's a better way.

That better way is *state machines*.

State machines formalize how we define and transition through the states of our application and give us ultimate control of the most complex parts of our apps.

In this course, we will explore the problems state machines purport to solve, like boolean explosion. We'll try to solve it our own way first, get so far, and then demonstrate how state machines get us all the way. After that, we'll dive into the XState library, JavaScript's premiere state machine library, to learn its API and how to use it to solve our problems.

By the time you're done taking this course, you should have a solid education about state machines and be able to start applying them.

Statecharts are a formalism for modeling stateful, reactive systems. This is useful for declaratively describing the behavior of your application, from the individual components to the overall application logic.

A large number of people are unable to use the web effectively due to an impairment or disability.

As developers there are several tools and techniques we can use to make our web applications accessible, ensuring a great user experience that includes everyone.

We all agree that Accessibility is important. However, it’s a broad landscape and can be overwhelming figuring out where to start!

Erin Doyle is an expert in creating accessible React applications and has developed a course that will give you a concrete process for testing, refactoring, and building your applications with accessibility in mind.

After this course, you'll have a jump start on auditing and fixing accessibility issues in your applications and gain a better understanding of your target users and how to approach your web app design from their perspectives.


Develop Accessible Web Apps with React

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!

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.

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

Rust is a modern language that is close to the metal. It's got the performance of C, but with a more friendly syntax and community.

It's also memory safe, and ensures your applications are bug free by catching errors at compile time instead of runtime.

These features make Rust a great choice for developing code for embedded systems, web servers, and CLI apps. You can even compile Rust into WebAssembly in order to run it in-browser!

But as the saying goes, "before you learn to run, you must learn to walk".

In this course, you will write your first Rust application.

Starting from “Hello World” you’ll quickly move on to learning about Rust’s types, configuration files, and the `cargo` package manager along with classics like functions, loops, and handling user input.

More Rust-specific concepts like macros and pattern matching will also be introduced.
