Docker containers wrap a piece of software in a complete filesystem that contains everything needed to run: code, runtime, system tools, system libraries – anything that can be installed on a server. This guarantees that the software will always run the same, regardless of its environment.

Zeit’s mission statement is to ‘Make Cloud computing as easy and accessible as Mobile computing.’ To that end, they’ve released some pretty amazing and powerful tools. In this course we’re going to take a look at `now`, their deployment tool, to see why it’s hands-down the simplest way to launch node applications, docker containers and even static files to the cloud.


We’ll also dig into some of now’s more advanced capabilities, including host aliasing, environment variables and integration with hosted databases.

The Chrome Developer Tools (DevTools for short), are a set of web authoring and debugging tools built into Google Chrome.

chrome-devtools

This course examines the Sources panel in the Chrome DevTools, which allows you to see what files are responsible for the various things on the screen. Bundled into this panel, though, is the single most useful tool for any JavaScript developer - the JavaScript Debugger. We’ll use the Debugger to inspect JavaScript as it runs, allowing you to watch (and even interact with) the state of your application as it runs in ways that’ll blow your mind if you’ve mostly used console.log to debug your applications to this point. 

Debug JavaScript in Chrome with DevTool Sources

If you are developing JavaScript applications you are likely using logging as an integral part of your development process. Did you know that you aren't limited to simple `console.log` statements? Modern browsers give you a lot more logging options to work with!

This course will explore those options and give you some new logging tools for your professional toolbox.

Advanced Logging with the JavaScript Console

In this course we’ll take a deep look at the Elements panel in the chrome devtools. We’ll step through each button and tab on this panel and discuss how to use them to interact with your web application as it runs.

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.

Most examples for reduce show you how to take an array of numbers and reduce them to a simple sum. Reduce is a great tool for this, but it can do so much more. It is a powerful tool, and essential to functional programming techniques.

This course will dig deep into the Array#reduce in JavaScript and give you a solid understanding to start using it today.

This course will examine the Network panel in Chrome DevTools. We’ll step through the request log, examining the various properties exposed. We’ll talk about timing, filtering, throttling and generally using the network panel to better understand the ways in which our applications exist within a connected context.

Ridiculously Easy Deployment with Now

A lot of characters have been spent talking about "engineering time" or about how to manage "engineering personalities", and many engineers may wryly chuckle at the archetype.

But advances in our understanding of neurodiversity mean it's time to look again at things like Autism, ADHD and other conditions that impact millions of undiagnosed people in various and often subtle ways.

Are you running on "Engineering Time" - or are you an undiagnosed neurodivergent person, likely with a number of unmet needs? Let's talk about it!

Check out the [community notes for the course](https://github.com/eggheadio/eggheadio-course-notes/tree/master/egghead-talks-things-every-software-engineer-should-know-about-neurodiversity).

Get more mileage from your console output by going beyond mere string logging - log entire introspectable objects, log multiple items in one call, and apply C-Style string substitution to make the console work for you.

Advanced Console Log Arguments

Organize your log output by grouping your logs into collapsable hierarchies using console.group().

Grouping and Nesting Console Log Output

We'll look at using array.reduce to transform an array of strings into an object that counts the occurrence of each string in the array.

Reduce an Array into a Single Object

Learn how to use the reduce function on javascript arrays to transform a list of values into something else. In this introduction we'll be taking a list of numbers and reducing them into a sum.

Transform an Array into a Single Value using Reduce

Learn how two common array functions - map() and filter() - are syntactic sugar for reduce operations. Learn how to use them, how to compose them, and how using reduce can give you a big performance boost over composing filters and maps over a large data set.

Use Reduce to Filter and Map over Large Datasets

Cascading Style Sheets bring order and beauty to our applications.

Learn how to use native CSS transitions to automagically add motion to your application. By specifying a simple transition rule, changes to the values of specific properties can be interpolated over time to give a graceful, polished look and feel to what used to be a jarring and sudden transition.

Introduction to CSS Transitions

`now` allows you to take your JavaScript (Node.js) or Docker powered websites, applications and services to the cloud with ease,
speed and reliability. In practical terms, any directory that contains a `package.json` or `Dockerfile` can be transported to the cloud with one command: `now`.


zeit-now

Use Zeit’s `now` to quickly and easily share static files by making them accessible to anyone with the URL.

Zeit allows you to expose the inner working’s of your deployment’s source code to aid in debugging or understanding how your code works. Learn how to configure and use this powerful window into your live behavior.

View source on your remote Zeit Now server

Often your project will require some secret keys or tokens - for instance, API keys or database authentication information. Learn how to safely and easily deploy secrets to now, and how to expose them as environment variables that your applications can load without making them public to the world.

Configure secrets and environment variables with Zeit’s Now

Learn a few advanced reduction patterns: flatten allows you to merge a set of arrays into a single array, the dreaded flatmap allows you to convert an array of objects into an array of arrays which then get flattened, and reduceRight allows you to invert the order in which your reducer is applied to your input values.

Learn to Flatten and Flatmap Arrays with Reduce

In this lesson, we will be looking at two common mistakes programmers make when working with `reduce.` We will see why we always need to pass in an initial value for our accumulator as well as return the accumulator.

Avoid Common Mistakes when Working with Reduce

Javascript has first-class functions which means that any function can stored, passed around, and returned just like an Object can. This allows for a lot of flexibility with how you call functions. This allows us to use array reduction to create functional pipelines by composing arrays of functions.
