Morten Rand-Hendriksen argues that CSS Grid changes web layout, showing how to place content in cells independent of HTML source order and reshape layouts with media queries. It makes the case for using Grid now that browsers support it.

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.

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.

A Netflix JavaScript talk on using Reactive Extensions (Rx) for asynchronous UI code. It covers Observables, composing events such as drag and drop, and sequencing Ajax requests.

Alex Russell's Chrome Dev Summit 2016 talk on building web experiences that work on slow, flaky networks and low-power devices. It argues developers should focus on the performance of real-world mobile hardware rather than desktop machines.

Jordan Walke, creator of React, talks at ReasonConf 2019 about the ideas behind ReasonML and how it extends React's programming model with OCaml. He also discusses why familiar syntax matters.
