Learn Elixir, Ionic and Jasmine

These videos include the introductory steps to writing your first Elixir function and beginning to understand some key concepts in Elixir that make it unique. 

Some of those concepts include:
- the Mix build tool
- project structure
- collections of functions written in modules
- function *arity*
- pattern matching and common uses for it
- the pipe operator

Elixir is a dynamic, functional language designed for building scalable and maintainable applications.

Elixir leverages the Erlang VM, known for running low-latency, distributed and fault-tolerant systems, while also being successfully used in web development and the embedded software domain.

Getting Started with Elixir

Theming Ionic applications is a topic that is often left undiscussed. Ionic has a robust API to theme your application so you don't have to settle with the default styles.

This course will show you how Ionic’s theming system works so that your application can have its unique look. It will explore the built-in utilities, which you can leverage directly.

You'll be introduced to the built-in CSS utilities that Ionic provides, Ionics grid system, and Ionic configuration settings to create a custom look and feel to your App.

Ionic is the beautiful, free and open source mobile SDK for developing native and progressive web apps with ease.

Style and Theme Ionic v3 Applications

Building native mobile applications has traditionally been a completely foreign work flow than web development. Recently frameworks, such as Ionic and React Native, have been come out to create a similar web development workflow in a native environment. 

Ionic 2 builds on top of Angular to offer a complete framework for building mobile apps using HTML, CSS, and Javascript that target native mobile and the browser. We’ll work with the RandomUser API to create an employee directory that will let us view user details, update that information, and pass the data back and forth with Ionic 2 routing.

Angular is a development platform for creating applications using modern web standards. Angular includes a wealth of essential features such as mobile gestures, animations, filtering, routing, data binding, security, internationalization, and beautiful UI components. It's extremely modular, lightweight, and easy to learn.

Building apps with Ionic 2

Ionic allows you to build cross platform native applications using Angular. In this course we will convert the Eggly AngularJS application into an Ionic mobile application.

AngularJS is an open-source JavaScript framework, maintained by Google, that assists with running single-page applications. Its goal is to augment web-based applications with model–view–controller (MVC) capability, in an effort to make both development and testing easier.

Welcome to the *Ionic Quickstart* series where you will learn how to get started with Ionic from the ground up. We will begin with how to install the required dependencies such as Node.js, Android SDKs and even GenyMotion to installing and running Ionic. By the time you finish, you will know how to create, edit and run an Ionic application. If you are on Windows or Mac and not sure where to start with hybrid mobile development, this is a great place to start!

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.

Creating cross-platform web-based applications with Ionic 4 and React is easy thanks to the Stencil compiler and `create-react-app`.

In this video, we look at how to use create-react-app and @ionic/react to make an Ionic 4 + React application

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.

Creating cross-platform web-based applications with Ionic 4 and Vue is easy thanks to the Stencil compiler and the Vue.js CLI.

We look at how to combine these together to use Ionic 4 components within our Vue.js applications.

Bootstrap a new Elixir project using Mix (a build tool included when you install Elixir), with its built in project generation.

Elixir code is organized into groups of functions called modules. You can create your own modules and built on top of predefined modules that are a part of Elixir by default.

Additional resources: 
- [Getting started with Modules and function from Elixir docs](https://elixir-lang.org/getting-started/modules-and-functions.html)

Write a New Function Inside of an Elixir Module

The syntax to pass arguments into functions is akin to many other languages. Elixir functions are uniquely recognized when running based off of the number of arguments passed in (a term called *arity*). This means you can define functions with the same name, so long as a different number of arguments is passed in.

Arity is a key concept to be aware of when reading documentation and writing your own code.

Additional resources:
- [Information about arity](https://elixir-lang.org/getting-started/modules-and-functions.html#function-capturing)
- [Default arguments in functions](https://elixir-lang.org/getting-started/modules-and-functions.html#default-arguments)

Pass arguments into Elixir functions and understand arity

Elixir uses `=` as an operator, but rather than assigning values to variables with it, it *matches* values on the right hand side of the `=` with the left side. This can be used in simple values, more complex data structures, and powerful condition checking.

Put into simpler terms, pattern matching is Elixir's way of assigning variables.

Additional resources:
- [Elixir docs on pattern matching](https://elixir-lang.org/getting-started/pattern-matching.html)

Pattern match values in Elixir

Some common uses for pattern matching in Elixir include checking conditions and passing parameters into functions. It's useful for pulling out only specific variables from collections of data.

In this lesson, we install the Android Software Development Kit (SDK) and the necessary Android API (Application Interface). This is the code base that allows us to run the Android platform on our PC. We also add a couple environment variables and update our PATH environment variable.

Install Android SDK for Ionic

In this lesson, we learn how to install Ionic and Cordova. We then build an app from scratch using the Ionic CLI and a blank starter template.
