    Ever write a long-ass Google Docs comment and then accidentally hit Cancel?🤦 Not all is lost. DevTools heap snapshots to the rescue! DevTools > Memory panel > Take snapshot. Expand the (string) item and peruse down the list. With luck, you'll find it.

    9 years ago, Panic put out Coda and its video tour became one of my web design favorites. As the 24fps video played, it was smoothly repositioned with 60fps CSS 3D transforms. Layers panel gives a nice behind-the-scenes.

    It's from a PR on 's popular Video Speed Controller extension. Basically: create an audio analyzer, read audio levels in realtime and adjust the playbackRate continuously to zip past quiet bits. Needs some polish but the idea is compelling.

    The Import On Interaction Pattern: ~ Lazy-load non-critical resources (e.g components, embeds) when a user interacts with UI that needs it.

    Import on interaction - a JavaScript loading optimization. This image shows a button being clicked or tapped and then code being downloded, data being fetched and then component code (or embed code) being rendered.
