Layered APIs と High Level API の標準化指針 | blog.jxck.io
Intro Extensible Web Manifest 以降、標準化作業は Low Level API にフォーカスし、一定の成果が出ている。 そこで、これらをベースとし、よりアプリレイヤの需要を満たすための High Level API をどう標準化するか、という点について指針が提案された。 基本は、Low Level API を元に Polyfill を作り、そこからのフィードバックにより策定を進めるという方針だ。 合わせて ES Modules の Import を用いて、polyfill とネイティブ実装をスムーズに切り替える拡張が提案されている。 本記事では Layered APIs (LAPIs) と呼ばれる、この一連の枠組みについて解説する。 また、同等の話を 東京 Node 学園 #tng30 で行った資料は以下である。 Web over Layered APIs St
BigInt: arbitrary-precision integers in JavaScript · V8
Show navigation BigInts are a new numeric primitive in JavaScript that can represent integers with arbitrary precision. With BigInts, you can safely store and operate on large integers even beyond the safe integer limit for Numbers. This article walks through some use cases and explains the new functionality in Chrome 67 by comparing BigInts to Numbers in JavaScript. Use cases #Arbitrary-precision
"last 2 versions" harmful
"last 2 versions" considered harmful There comes a time in every developer's life when they come to realize their thoughtleaders misled them. Oh, we've really done it now. So remember how we told you all to use babel-preset-env? { "presets": [ ["env", { "targets": { "browsers": [ "last 2 versions" ] } }] ] } See browserlist coverage We told you to use it because it would only compile the things th

When building a modern web experience, it's important to measure, optimize, and monitor if you're to get fast and stay fast. Performance plays a significant role in the success of any online venture, as high performing sites engage and retain users better than poorly performing ones. Sites should focus on optimizing for user-centric happiness metrics. Tools like Lighthouse (baked into web.dev!) hi
An experimental data-flow analysis tool for front-end JavaScript
What is FromJS? FromJS shows you where each value in the DOM comes from. For example, some data might have been loaded using fetch, some might have been stored in localStorage, and some might have been hard-coded in the JavaScript code. Try FromJS I've not worked on this for a while and it never worked super well, so maybe you shouldn't actually try it :) Install from NPM: npm install -g @fromjs/c
SmooshGate FAQ | Blog | Chrome for Developers
What the smoosh happened?! A proposal for a JavaScript language feature called Array.prototype.flatten turns out to be Web-incompatible. Shipping the feature in Firefox Nightly caused at least one popular website to break. Given that the problematic code is part of the widespread MooTools library, it’s likely that many more websites are affected. (Although MooTools is not commonly used for new web
