    • @………’s advice on when to use @extend vs a mixin (in Sass), post w/ examples
      • Use @extend to share traits among inherently related rulesets (e.g. .btn-positive and .btn-negative). Use mixins (without arguments) to repeat a group of declarations throughout your codebase (in unrelated rulesets).

    • Optimizing delivery of ES6 modules over HTTP/2 w/ a “dependency cache”, @………’s 8-min preso
      • “The remaining perf issue is the round trip latency required to load deep dep’s, as we only find out the dep’s of a module once we have fetched that module, before fetching its dep’s in turn. We can get around this by injecting the full dependency tree upfront into a dependency cache, so that all dep’s can be fetched in parallel.” (docs)
