A really old JavaScript guide that many people link to in all sorts of contexts is Addy Osmani's fantastic Learning JavaScript Design Patterns. If you've never seen it, then by all means, bookmark it and check it out when you get a chance. Or just keep it in an open tab and try to study one of the patterns once in a while, maybe once or twice a week.

If you've seen it before, then I'm sure you're thinking it's just an old resource that might not be as applicable to modern JavaScript. That was true a few years ago, but as the main page points out, "This edition was updated to ES2015+ syntax in 2021."

Learning JavaScript Design Patterns

The content has been updated, but it's also been moved from Addy's personal website. It's now hosted as a sub-resource on Patterns.dev, a more recent project of Addy Osmani and Lydia Hallie. The new book is described as, "a free book on design patterns and component patterns for building powerful web apps with vanilla JavaScript and React."

Learning JavaScript Design Patterns

I think it's great that such an old and important JavaScript resource is still fresh in 2022, but it's especially nice that it's now part of a much larger project. And just to be clear: The original JS Patterns book is not part of the new book; it's part of the website for the new book.

As a side point, maybe you're wondering how these well-researched publications can possibly be offered for free. I'm sure there was literally hundreds of hours of research that went into all the content.

In case you're not aware, Addy works on Google Chrome, mostly focused on web performance. Making the web fast makes more money for Google. Therefore, there's huge incentive for someone like Addy to put out free information on making the web faster. Of course, speed makes more money for any app that's fast, so there's incentive for all of us to use the suggestions.

Now on to this week's tools!
