Manuel Matuzovic has an excellent write-up of his modern HTML boilerplate.

I really enjoy reading these back-to-the-basics type posts because I almost always learn about some new feature that I wasn't aware of before. This post was no exception. In particular there's a lot to know about icons and image previews that I now want to integrate into all of my projects.

Shout out to Lea Verou for sharing Node.isConnected. I've had a few cases where I've needed to determine if a node is in the DOM. I've usually written something along the lines of:

const inDOM = (node) => {
  for (let n = node; n; n = n.parentNode) {
    if (n === document) {
      return true;
    }
  }
  return false;
};

Having a native property for this will be helpful.

This is an excellent overview of using the Web Animation API.

I meant to share this a month ago when I first saw it, but it came up again recently when I was making some animation improvements to a website I've been working on, so there's no time like the present.

I made some minor changes to the animateTo function included in the video for my own purposes, so the snippet I use is along the lines of:

function animateTo(element, keyframes, options) {
  let cleanup = () => {};
  return new Promise((resolve, reject) => {
    try {
      const animation = element.animate(
        keyframes,
        {
          ...options,
          fill: 'both',
          signal: undefined
        }
      );

      const finish = () => {
        try {
          animation.commitStyles();
          animation.cancel();
          resolve();
        } catch (e) {
          // handle browsers that don't support `Animation.prototype.commitStyles`
          reject(e);
        }
      };
      animation.addEventListener('finish', finish);

      // While the animation is not exposed through `animateTo`,
      // animations can still be cancelled via the `signal` option,
      // or when accessed from `Element.prototype.getAnimations`
      const cancel = () => reject();
      animation.addEventListener('cancel', cancel);

      // Add support for AbortController
      const signal = options.signal;
      const abort = () => animation.cancel();
      if (signal) {
        signal.addEventListener('abort', abort);
      }

      cleanup = () => {
        animation.removeEventListener('finish', finish);
        animation.removeEventListener('cancel', cancel);
        if (signal) {
          signal.removeEventListener('abort', abort);
        }
      }
    } catch (e) {
      // handle older browsers that don't have `Element.prototype.animate`
      reject(e);
    }
  }).finally(cleanup);
}

I meant to share this a couple months ago when I first read it. It's an excellent breakdown of some of the differences between software engineer levels and the type of work expected.

As a tangent, Bonnie Eisenman uses the following roles for the various different levels:

• junior
• midlevel
• senior
• staff

I like that Bonnie chose to label the various levels numerically. I prefer to use numeric levels when possible, as it helps to avoid some bias when someone switches to tech late in their career and takes on a "junior" role. Unfortunately there's no real standard for numeric levels.

My preferred labels are along the lines of:

• level 0: intern/co-op
• level 1: junior
• level 2: midlevel
• level 3: senior
• level 4: staff

Anyway, go read Bonnie's post.

Alex's "Do not get arrested challenge 2020" is the best thing I've read all week.

Somewhere around:

I called at least 30 phone numbers, to say nothing of The Emails. If you laid all the people I contacted end to end along the equator, they would die, and you would be arrested.

I laughed so hard I nearly fell out of my chair.

I've seen James Hong's performances many times, but they only account for a tiny portion of his extraordinary number of roles.

I first started recognizing him after his voice acting for Covetous Shen in Diablo III. He really leaned into the rich texture of his voice for Shen, which made Shen stand out as particularly memorable to me. Every time James appears in a TV show or movie I'm watching, I think to myself "It's Covetous Shen!"

This will be a great tool if it gets standardized and implemented. I've had a few projects where heading and paragraph spacing were important for their design systems, and this would have come in handy rather than needing to rely on a handful of work-arounds and approximations.

Nice to have some new music.

I've been using Git for years, but I've never been great with Git CLI or really understood the inner workings.

Julia Evans does good work, so I'm definitely going to check this out.
