On 23/1/2025, Opher Vishnia lectured about React Performance during a JavaScript Israel Meetup. Abstract: Your React app is slow, and, yes, it’s kind of your fault.

On 26/12/2024, Gil Tayar lectured about Module Resolution during a JavaScript Israel Meetup. Abstract: Module resolution is at the heart of JavaScript - how JavaScript finds the file that is referenced in the import. But how this works is opaque to most of us. It works… until it doesn’t, and then the build fails with weird errors that you don’t know how to fix. This talk will explain in detail how module resolution works in the browser, in Node.js (for ESM and CommonJS), and also in bundlers and TypeScript. It will explore things like CJS vs ESM, package.json exports vs main, conditional exports, aliases, and others.
