web-share-target VS caniuse

This is not a web standard. Google wrote the specification and only Google have implemented it. It’s an unofficial draft:

> Editors:

> Matt Giuca (Google Inc.)

> Eric Willigers (Google Inc.)

> Status of This Document

> This specification was published by the Web Incubator Community Group. It is not a W3C Standard nor is it on the W3C Standards Track

Firefox doesn’t implement it either: https://bugzilla.mozilla.org/show_bug.cgi?id=1476515

Apple raised a concern about spoofing which seems to have gone unaddressed by the spec authors in over a year: https://github.com/w3c/web-share-target/issues/109

This may yet turn into a web standard given more work, but please don’t hold up a Google spec. implemented only by Google as if it were a part of the web platform that Apple are late in implementing.

Can I X, is a question about the readiness/compliance of a certain thing at time = now. Can I use CSS version X was the iconic early meme.

For a generalized example, if you wanted to know if the basketball courts were ready for you to “ball it up” in a certain city, it’d be caniball.com

If you want to know if you can use a certain frontend technology, the idea is like: canwefigma?

It’s a glorified feature matrix, and usually a project of a passionate community. I approve, even if some of the memes are a bit dank.

https://caniuse.com/ is a popular tool to check what web features are working across different browsers - "can you use this and assume that it will work for others".

The article uses custom css @properties which are awesome and have 88% browser support [1].

One thing to watch out for is differences in how browsers handle setting the fallback initial-value. Chrome will use initial-value if CSS variable is undefined OR set to an invalid value. Firefox will only use initial-value if the variable is undefined. For most projects, this won't be an issue, but for a recent project, I ended up needing to use javascript to set default values in Firefox to iron out the inconsistency between browser implementations.

You forgot to mention (Web)Workers. This is explicit creation, management, and communication with additional threads within JavaScript. What's more, they've been around in JavaScript longer than the V8 engine has even existed!

Do you happen to know where can I check out the cutoff version for each browser? https://caniuse.com/?search=wasm doesn't have it (or other things like WasmGC for that matter)
