    Today I learned you can add ".todo" after a test with just a description to mark a test as "to do". Great for TDD! (Though I wish I could also use this on existing tests during a refactor) teaching cred to ,

    The `git checkout` command was confusingly named and too overloaded in functionality. “How do I switch to a branch?” - checkout “How do I restore a file to a previous version?” - checkout Enter Git 2.23: - `git switch <branch>` - `git restore <file>`

    This is why i don't trust frameworks claiming to be fast b/c they score 👍 benchmarks. This is React in concurrent mode, facing an impossible(!) amount of load (2000 state-connected comps getting re-rendered with fresh props 60 frames/sec). The scheduler makes that a stable 60fps

    I'm tired of demos. It's time to see if this async version of React really works. I flipped it on in my (changed 5 lines of code) and this is the difference. It completely changes the user experience. There's a lot of little things left to do, but this is huge. Awesome work.

    How do you iterate through a range of dates with plain old ? Share your approach :)

    const forEachDateInRange = (
  { startDate, endDate },
  callback
) => {
  const current = new Date(startDate);
  let index = 0;

  while (current <= endDate) {
    callback(new Date(current), index);

    current.setDate(current.getDate() + 1);
    index++;
  }
};

    Parcel 2 can now build entire monorepos! Each package defines "source", "main", "module", and "types" in package.json and Parcel outputs CommonJS, ES6, TypeScript declarations, and CSS. 🚀 We even tree shake the .d.ts files! 🤯
