Dan Abramov live-codes hot reloading with time-travel debugging at React Europe 2015, debuting Redux and its devtools. The slides themselves are driven by application state.

Tom7 explains how he built a SIGBOVIK 2017 paper made only of printable ASCII bytes that is also a valid DOS executable. He writes a C compiler targeting printable x86 without self-modifying code and solves the puzzles the constraint creates.

Brian Lonsdorf explains why Underscore.js falls short as a functional programming library, then introduces currying, composition and point-free style in JavaScript. He argues for data-last argument ordering.

Chris McCord's ElixirConf EU 2019 keynote introducing Phoenix LiveView, which builds interactive server-rendered apps without writing JavaScript. It explains how only changed dynamic parts are sent over a websocket.

Okta developer advocate Nate Barbettini explains OAuth 2.0 and OpenID Connect in a roughly hour-long talk. It starts from the problems the protocols solve and walks through the flows. The description notes the implicit flow material is now out of date.

Morphcat Games explains how they fit Micro Mages, a full-featured NES game, into 40 kilobytes. It covers compression of sprites and level layouts and other space-saving tricks.

Jake Archibald's JSConf.Asia 2018 talk "In the Loop" explains the browser event loop, covering tasks, microtasks, requestAnimationFrame, and how rendering interleaves with JavaScript. It uses visual walkthroughs to show why code runs in surprising orders and why setTimeout fixes are unreliable.

Cal Henderson's DjangoCon 2008 keynote, "Why I Hate Django", is a funny critique of Django from a Flickr architect. It touches on scaling topics such as database replication.

Evan Czaplicki, creator of Elm, talks at Curry On 2015 about user-focused language design. He explains the principles behind Elm and how to make a functional, typed language as approachable as JavaScript.

Evan Czaplicki's Strange Loop 2014 talk surveys the many formulations of functional reactive programming and how they relate historically and theoretically. It then shows how Elm's variant enables hot-swapping and its time-traveling debugger.

Pete Hunt of Facebook and Instagram presents React at JSConf.Asia 2013, explaining its design principles and why they seemed shocking at first. He argues that React separates concerns rather than technologies, and the talk also announces the React Chrome developer tools.

Ryan Dahl, the creator of Node.js, introduces the event-driven I/O framework built on V8 with examples, and discusses the v0.4.0 release and its new APIs.

Steven Wittens' JSConf US 2013 talk on drawing with WebGL, using animated visuals to walk through vectors, matrices and the rendering pipeline. Despite the title, it works as a visual primer on the linear algebra behind 3D graphics.

Cheng Lou's react-europe 2016 talk lays out a mental framework for thinking about abstraction levels in JavaScript tooling, from Angular and Grunt to Webpack and React. It uses that framework to reason about the cost of abstractions and how to choose between competing solutions.

Facebook engineers explain why they abandoned the traditional MVC paradigm for a more functional architecture, introducing Flux and React. They use the unread-message-count bug as a case study of the problems of bidirectional data flow at scale.

Dylan Beattie's entertaining NDC talk imagines an alternate history of the web, asking what if different decisions had been made on operating systems, browsers and standards. It blends real history with humor.

James Mickens's 2015 Harvard colloquium argues that browsers are bloated and insecure because feature races trump clean interface design. He presents a cleaner, more secure browser architecture (Atlantis) with a much smaller API surface.

Lee Byron of Facebook explains how persistent immutable data structures work and how to use them in React apps with Immutable.js. He covers memoization benefits and avoiding coupling through shared mutable state.
