Array Iteration

https://gist.github.com/ljharb/58faf1cfcb4e6808f74aae4ef7944cff

While attempting to explain JavaScript's reduce method on arrays, conceptually, I came up with the following - hopefully it's helpful; happy to tweak it if anyone has suggestions.

Intro

JavaScript Arrays have lots of built in methods on their prototype. Some of them mutate - ie, they change the underlying array in-place. Luckily, most of them do not - they instead return an entirely distinct array. Since arrays are conceptually a contiguous list of items, it helps code clarity and maintainability a lot to be able to operate on them in a "functional" way. (I'll also insist on referring to an array as a "list" - although in some languages, List is a native data type, in JS and this post, I'm referring to the concept. Everywhere I use the word "list" you can assume I'm talking about a JS Array) This means, to perform a single operation on the list as a whole ("atomically"), and to return a new list - thus making it mu

NOTE: This is no longer an experiment! You can use the accessibility inspector in Chrome Devtools now, including a fantastic color contrast inspection tool. Read more: https://developers.google.com/web/updates/2018/01/devtools#a11y

Just like any good element inspector helps you debug styles, accessibility inspection in the browser can help you debug HTML and ARIA exposed for assistive technologies such as screen readers. There's a similar tool in Safari (and reportedly one in Edge) but I like the Chrome one best.

As an internal Chrome experiment, this tool differs from the Accessibility Developer Tools extension in that it has privileged Accessibility API access and reports more information as a result. You can still use the audit feature in the Chrome Accessibility Developer Tools, or you could use the aXe Chrome extension. :)

To enable the accessibility inspector in Chrome stable:

Getting Started

These instructions will get you a copy of the project up and running on your local machine for development and testing purposes. See deployment for notes on how to deploy the project on a live system.

Prerequisites

Note: There is a lot of information here, but if I have provided a link, it is probably something you should click on and read. OAuth is a complex enough subject on it's own, and hacking these two services together only adds to it.

Even so, I have found Firebase's API to be simpler than almost any other OAuth solution I have explored. When all is said and done, the important bits of code related to authentication is actually less than 10 lines. If you have ever tried to implement your own OAuth flow before, you know how amazing that is.

In the end, it may be worth using Firebase for authentication, even if that's the ONLY thing you use it for.

Polygit

Polygit is deprecated and only compatible with Bower and Polymer 1.0 & Polymer 2.0. As an alternative, use this Glitch to load dependencies via Bower.

Polygit serves files directly from github (via cdn.rawgit.com) in a manner that is compatible with HTML Imports natural deduplication feature.

Examples:
