Shipping Temporal
The Temporal proposal provides a replacement for Date, a long standing pain-point in the JavaScript language. This blog post describes some of the history and motivation behind the proposal. The Temporal API itself is well docmented on MDN. Temporal reached Stage 3 of the TC39 process in March 2021. Reaching Stage 3 means that the specification is considered complete, and that the proposal is read
Accelerating Large-Scale Test Migration with LLMs
By: Charles Covey-Brandt Airbnb recently completed our first large-scale, LLM-driven code migration, updating nearly 3.5K React component test files from Enzyme to use React Testing Library (RTL) instead. We’d originally estimated this would take 1.5 years of engineering time to do by hand, but — using a combination of frontier models and robust automation — we finished the entire migration in jus
あらためて理解するArrayBuffer - JavaScriptでバイナリデータを扱う方法 - ICS MEDIA
配列（Array）との比較 JavaScriptにはTypedArrayとは別に配列（Array）の違いを説明します。 ArrayはTypedArrayと比べると柔軟で汎用性が高いです。しかし、Arrayは内部で動的なメモリー管理を行うため、データ処理や転送を高い頻度で行う場合にはオーバーヘッドが発生する可能性があります。 TypedArrayは長さが固定であり、バイト単位のデータ格納が可能なため、メモリーアクセスが効率的に行われます。数値計算においてもバイナリデータを直接操作できるので、高いパフォーマンスが期待できます。また、メモリー領域が連続しているので高速なデータの転送が可能です。 大量のデータを処理する数値計算の場合にはTypedArrayで管理するとデータのまとめた取り回しが楽になります。逆にデータの規模が小さい時は汎用的なArrayが良いでしょう。 TypedArrayは決まっ

Land ahoy: leaving the Sea of Nodes · V8
V8’s end-tier optimizing compiler, Turbofan, is famously one of the few large-scale production compilers to use Sea of Nodes (SoN). However, since almost 3 years ago, we’ve started to get rid of Sea of Nodes and fall back to a more traditional Control-Flow Graph (CFG) Intermediate Representation (IR), which we named Turboshaft. By now, the whole JavaScript backend of Turbofan uses Turboshaft inste
Modern Cookie Management with the Cookie Store API
Learn how the Cookie Store API modernizes cookie management with async operations and event handling for efficient, error-free web development. The browser Cookie Store API represents a modern approach to handling cookies in web applications. The way we’ve always done it is using document.cookie which is error-prone because you have to work with key/value pairs in a string. Besides being error-pro
