Highlights from this week

This week was all about moving external code into the docs repo, tidying, and pushing on our ongoing cleanup efforts across MDN:

I reviewed and submitted several PRs to move external examples into the repo. In general, we want to replace JSBin, JSFiddle, and CodePen embeds with live samples in the page. When you use the MDN live sample system, we get linting, better code search, and the presentation and interaction is a lot better. We have MDN playground support, so people can break out the integrated editor, and the overall look and feel of the site is improved.

I also continued the sidebar migration work: moving macros for the addons (web extensions) docs and the CSS section into front matter for easier maintenance and localization.

Summary

I worked on 32 total pull requests, including 6 created and 26 reviewed, across 4 repositories.

Most active day: 2025-07-14, with 19 PRs.
