GitHub - ulid/javascript: Universally Unique Lexicographically Sortable Identifier
ULIDs are unique, sortable identifiers that work much in the same way as UUIDs, though with some improvements: Lexicographically sortable Canonically encoded as a 26 character string, as opposed to the 36 character UUID Uses Crockford's base32 for better efficiency and readability (5 bits per character) Monotonic sort order (correctly detects and handles the same millisecond) ULIDs also provide: 1
Trust is good, observation is better: Intersection Observer v2 | Articles | web.dev
const onIntersection = (entries) => { for (const entry of entries) { if (entry.isIntersecting) { console.log(entry); } } }; const observer = new IntersectionObserver(onIntersection); observer.observe(document.querySelector('#some-target')); What's challenging with Intersection Observer v1? To be clear, Intersection Observer v1 is great, but it's not perfect. There are some corner cases where the A

Future JavaScript: what is still missing?
In recent years, JavaScript has grown considerably in size. This blog post explores what’s still missing. Notes: I’m only listing the missing features that I find most important. Many others are useful, but there is also a risk of adding too much. My choices are subjective. Almost everything mentioned in this blog post is on TC39’s radar. That is, it also serves as a preview of a possible future J

JavaScriptの正規表現の戻り読みはPerlのそれよりも表現力が高い: Days on the Moon
ECMAScript 2018で正規表現の戻り読み(lookbehind)が追加されました。 /(?<=foo)bar/.test('foobar'); // => true 'foobar'.replace(/(?<=foo)bar/, 'baz'); // => 'foobaz 正規表現の戻り読みと言えばPerlでは1998年7月リリースのバージョン5.005からサポートしており、そこから20年もたってと思いたくなるかもしれません。しかし、ECMAScript (JavaScript)のそれはPerlのものとは一味違います。なんと戻り読みの中で量指定子(*、+、?、{n}など)を使えるのです。 // JavaScriptなら(?<=...)の中で+が使える。 /(?<=fo+)bar/.test('foobar'); // => true # Perlでは(?<=...)の中で+を使お
Introducing Background Fetch | Web | Google Developers
In 2015 we introduced Background Sync which allows the service worker to defer work until the user has connectivity. This means the user could type a message, hit send, and leave the site knowing that the message will be sent either now, or when they have connectivity. It's a useful feature, but it requires the service worker to be alive for the duration of the fetch. That isn't a problem for shor
GitHub - swc-project/swc: Make the web (development) faster
Make the web (development) faster. SWC (stands for Speedy Web Compiler) is a super-fast TypeScript / JavaScript compiler written in Rust. It's a library for Rust and JavaScript at the same time. If you are using SWC from Rust, see rustdoc and for most users, your entry point for using the library will be parser. Also, SWC tries to ensure that If you select the latest version of each crates, it wil
