The first three talks from React Conf 2018, by Sophie Alpert, Dan Abramov and Ryan Florence. They introduce React Hooks and explain the problems with classes that hooks solve.

Pete Hunt of Facebook and Instagram introduces React at JSConf EU 2013 and explains its design principles. He argues that separating templates from logic only separates technologies, not concerns, and makes the case for components.

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.

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.

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.

Lin Clark gives an illustrated, cartoon-style walkthrough of React Fiber, the rewrite of React's reconciler, explaining its incremental rendering and scheduling at React Conf 2017.

Pete Hunt explains why React's virtual DOM was built, how it compares with databinding-style systems, and what it means for future browser technology. Recorded at FutureJS 2014 in Barcelona.

Jafar Husain of Netflix explains at React.js Conf 2015 how Netflix runs React-style rendering without the DOM on smart TVs and game consoles. It uses a canvas-like API for performance.

Andrew Rota of Wayfair argues at React.js Conf 2015 that React and native Web Components complement each other. He shows how they can be combined for complex web applications.

Ben Alpert of the React team talks at React.js Conf 2016 about where React is heading. He covers performance and stability work, challenges at Facebook, and opportunities such as bringing React Native ideas to the web.

Ryan Florence's React.js Conf 2015 talk pushes React into unusual use cases, including a demo comparing rendering in React, Ember and Angular.

Svelte creator Rich Harris explains moving reactivity into the compiler and language rather than tracking state at runtime, with a history of spreadsheets as reactive systems and comparisons to React.

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.

Dan Abramov's JSConf Iceland talk on what came after React 16, with live-coded prototypes of async rendering and time slicing. It previews the ideas that became concurrent mode and suspense.

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.

Kirk Sorensen's Google Tech Talk on thorium molten-salt reactors (LFTR). He covers why the technology was shelved after early development and argues that now is the right time to revisit it.

A five-minute lightning talk from React.js Conf 2016 by Elie Rotenberg on protecting the DOM from tampering. It shows how React tree obfuscation (react-armor) can shuffle class names, tags and tree structure to defeat CSS-selector-based ad blocking.

An episode of REACT in which children try to figure out 1970s-1980s computers, including an Apple II and floppy disks. It was made to promote the AMC show Halt and Catch Fire.

Jafar Husain's ACM keynote presents Netflix's JSON Graph and Falcor, which let web developers treat all cloud data as one virtual JSON model. It combines reactive programming with REST principles.

A REACT episode where teenagers try Windows 95 for the first time and react to the retro interface and technology.

Tom Dale explains the internals of the Glimmer VM, Ember's rendering engine, which compiles templates to opcodes. The talk includes a performance benchmark demo.

A short clip of the audience at Valve's 2017 announcement of Artifact, a Dota 2 card game, reacting with visible disappointment. The footage captures the awkward silence and the logo reveal.

A professor from Illinois compares the cost of building, fueling and operating a nuclear plant against a natural gas plant, using visual charts. It shows how construction time and interest rates dominate, when the investment pays off and when costs cross over.

A short Bloomberg clip from the 2018 UN General Assembly. Trump warns that Germany will become dependent on Russian energy, and German delegates are shown reacting with laughter.

Rick Falkvinge responds to viewer feedback on his earlier Lightning Network video and raises a flaw he says was not previously discussed. The main thread is the network's unsolved routing problem.

A one-minute clip from a cat cafe in Japan where sleeping cats wake and look around just before an earthquake begins shaking the room.

A Downfall-style parody in which Hitler rages about functional programming concepts such as monads and Haskell. It runs about four minutes.

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.

A 2011 remix of over six hours of talks by Kirk Sorensen and other thorium advocates, explaining thorium as a nuclear fuel and the liquid-fluoride thorium reactor (LFTR). It argues LFTRs could produce energy without long-lived transuranic waste.

Sebastian Markbage explains how React is moving toward a minimal API surface by leaning on language features and patterns instead of dedicated framework APIs. He also touches on JSX and syntax proposals for future JavaScript.

Tom Occhino and Jordan Walke present how Facebook builds JavaScript apps, in the talk where React was first publicly announced at JSConf US 2013.

A long documentary-style film on the 1961 SL-1 reactor accident, where a control rod was withdrawn too far and the reactor went prompt-critical. The resulting steam explosion ejected control rods and shield plugs.

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.

A demo of the Cubli, a 15 cm cube that uses reaction wheels to jump up onto a corner, balance there and fall in a controlled way to move. The video shows these three abilities chained into locomotion.

Yaron Minsky of Jane Street shows how the OCaml Incremental library lets trading UIs express data transformations that are easy to read and efficient on streaming data. It includes a live table demo.

A Ukrainian documentary about the liquidators who cleaned radioactive debris off the Chernobyl reactor roof in two-minute shifts. It presents their firsthand accounts and footage of the work.

MIT 22.01 lecture by Michael Short explaining the Chernobyl accident technically, including RBMK reactor positive feedback, xenon poisoning and the cascade of human errors during the test.

A SciShow episode in which Hank Green introduces five of the most dangerous chemicals, from lethal toxins to substances that explode on contact. It is an entertaining overview of extreme chemical hazards.

Richard Feldman describes introducing Elm into a mixed React and jQuery front-end in production, and why the result was reliable, clean and fast enough to make the back-end team jealous.
