Rafal Dittwald's Clojure/north talk shows how to move from writing Java-style code in Clojure to thinking in data-driven, functional terms. He walks through a JavaScript example, refactoring imperative code step by step into a functional core.

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.

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.

Raymond Hettinger's PyBay 2017 keynote on concurrency in Python. It covers threads, processes, asyncio, locks and the GIL, with live shell-based examples.

Ron Pressler's Curry On 2015 talk arguing that imperative languages should not be polluted with pure functional concepts like monads. He favors simple blocking code over non-blocking styles.

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.

Derek Slager's Clojure/conj talk argues that ClojureScript is a pragmatic choice for web development. He addresses common objections, recent improvements, tooling and use cases where it shines.
