LightningOnDemand revives a pulsed Lorentz plasma cannon, using modern capacitors to extend its range and increase the delivered energy. It is a high-voltage, high-current hobby demonstration.

Veritasium explains why a halved grape in a microwave makes plasma: the grape traps microwaves, and the fields of two halves interact to concentrate energy where they touch.

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.

Asianometry explains the EUV light source inside ASML's lithography machines, where lasers hit falling tin droplets twice to produce 13.5 nm light. It walks through the engineering of the droplet generator, the pre-pulse and main laser, and the plasma that results.

Brian Peiris demonstrates RiftSketch, a web app where you write JavaScript with Three.js while wearing an Oculus Rift and watch the world around you change live. It runs on Firefox builds with WebVR.

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.

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.

Tsoding live-codes a JSON parser from scratch in Haskell in about 111 lines, using only the standard library. It is an edited Twitch stream that explains the intuition behind parser combinators, functors, applicatives and monads.

A three-minute clip in which Douglas Crockford explains why he allowed the JSLint reference implementation to be used for evil. It recounts the license clause and how corporate lawyers reacted.

Brian Leroux's dotJS 2012 talk WTFJS is a quick, humorous tour of JavaScript's odd behaviors and quirks.

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.

Rasmus Lerdorf marks 25 years of PHP at phpday 2019 with a look at the highlights and lowlights of the language. He argues for upgrading PHP versions, covering performance, static analysis, zero-cost profiling and dead code elimination.

A short video built around Douglas Crockford, creator of JSON, saying JavaScript is a flawed language and that developers should eventually move on from it. It is a brief commentary clip with little technical detail.

Philip Roberts explains the JavaScript event loop, call stack, callbacks and asynchronous behavior with live visualizations using a tool he built. It demystifies terms like non-blocking and single-threaded.

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.

A JSConf 2014 talk visually breaking down algorithms behind everyday UI patterns, such as dropdown menus that vanish when the mouse drifts and picking the nearest target to the cursor. It shows how these are implemented in JavaScript.

Douglas Crockford's Nordic.js 2014 talk on 'the better parts' of JavaScript and programming in general. He argues against `this`, `new` and ES6 classes, and for classless, composition-based object patterns, with some broader remarks on building better structures for the future.

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.
