💡 TIL about static initialization blocks in JS classes.
I've been writing JavaScript for almost 15y now, and there's always something new to learn. To be fair, I don't use JavaScript classes often, but static initialization blocks are very neat for the dynamic setup of other static properties.

TIL recap: Not too long ago, I learned that you can put "nameless static" blocks into ECMAScript classes. What for?
A static initialization block runs when the ECMAScript class is initialized (don't confuse this with using the class to create a new instance).

Web Component folks:
What’s the current thinking / guidance on how one can and should create a new instance of a WC in JS?
Specifically curious about creating elements via `new MyElement()` — is that considered a no-no?

I was extremely surprised to discover that hidden is actually implemented as basically [hidden]{display:none} in the user stylesheet, meaning that if you do myelement{display:grid} <myelement hidden>, it isn't hidden. So I already tend to assume that <element hidden> won't work :(

Sure, that's what I'm proposing.
Straw example: A `myElement.__devtoolsData__` property which gets visualized in DevTools above all the other random properties for that node.
Any framework (WC or not) could put developer-defined data there and highlight the parts which matter to them.

Bonus question:
What about passing parameters into that class creation — i.e. `new MyElement(p1, p2, p3)`?
*Assume there’s logic that will check for the existence of the params and fallback to search for attr/prop values in the case where the WC is created via `document.createElement`

If you are using #typescript, both !. (non nullish assertion operator) and ?. (optional chaining operator) may seem similar (probably just me). But they server difference purposes. You use !. to tell the compiler that you are certain that a value is not null or undefined. [image_1] The ?. (1/3)

Vanilla JavaScript Equivalent jQuery Tasks Replaced for Performance
Let’s be honest: jQuery has been a lifesaver. For years, it smoothed over the rough edges of cross-browser inconsistencies, particularly with older versions of Internet Explorer. But today, developers have plenty of vanilla javascript equivalents to jQuery for common tasks like selecting elements, handling events, manipulating classes, and updating the DOM. Writing $('#myElement').hide() once felt like magic compared to the verbose native alternatives, but modern browsers now provide powerful APIs that can handle many of these tasks without relying on a library.

Does anyone know why web components using the `is=<tag-name>` breaks when you try to use a constructor at super()? It seems like the browser is trying to construct a new `MyElement` instance, but since the tag name is different than the original element it freaks out?

…new ways of building WCs enter the fray.
These new methods are very much influencing the types of WCs I’m seeing in the wild — some of which make solid usage of JS DOM APIs.
With that said, the use of `new MyElement` is definitely something I see very very very rarely.
So again agree/disagree.
