What if we could mutate data *and* get all the data back we need to properly update the UI in just one network round-trip?
This guide serves as an introduction to learning JavaScript, covering necessary prerequisite knowledge and addressing common obstacles. It highlights JavaScript’s origins, essential concepts, and practical applications across different environments.
You can limit how far the background-image of an element applies by using background-clip. That means you can apply *different* backgrounds to, say, the padding and border.
The post discusses the drawbacks of null references in programming and introduces the Optional type as a solution, particularly in Java. The Optional type helps avoid null reference exceptions by allowing safe interaction with absent values using methods like ifPresent, ifPresentOrElse, map, and flatMap.
Now that we’re starting to see better support for @starting-style and the allow-discrete keyword, we’ve got a pretty straightforward way for defining *different* entry and exit states.
These are our recommendations for those of you early in your web developer journey. This is about tech and the real world stuff around it that you’ll need.

Do you need a 3rd party testing library like jest? Maybe, but there is a tester built in now. Do you need a 3rd party file watcher like chokidar? Maybe, but there is a built-in watcher now. Do you need a build process to deal with TypeScript? Not anymore. Do you need chalk to colorize/style terminal output? Not anymore.
Bluesky is enjoying a boon in popularity. The API access right now is nicely open, allowing people to create some interesting stuff around it. I like this idea from Matt Kane: a Web Component (<bluesky-comments>) that loads up all the replies to any particular post like a comment thread. Imagine there is a post for every blog post you publish (like we do), instead of writing your own comment system you could just say “leave a reply on Bluesky” and that could be the whole commenting system. I hope get gets proper filtering.
I’ve seen other websites for helping you generate cubic-bezier() values in CSS for animations and transitions, but Easing Wizard is the best. Importantly, it helps you with the newer linear() style timings as well, which are more powerful. All the different types, the presets, the customization options, the different styles of previews, the clean design… outstanding work from Matthias Martin.
