Imports are not code – they're declarations
Sam and Ryan talk about a confusing situation where moving code into an ES module changed the execution order of a program. They also talk about conflicting advice over whether React's useEffect is appropriate for writing data, and chat about PostCSS, Tailwind and build tools.
Topics include:
- 2:31 – Tailwind, PostCSS, and low-level vs. high-level tools
- 13:12 – Mirage JS and Cypress
- 13:55 – Ember 3.13 and Octane
- 15:28 – Ryan's experiencing upgrading EmberMap from 3.4 to 3.12
- 20:19 - ES Modules, and learning that imports are not code
- 42:12 – React and useEffect, and the difference between reads and writes vs. rendering and event handlers
- 1:00:50 – Object-oriented vs. functional programming in JavaScript
