Why do browsers throttle JavaScript timers?
Even if you’ve been doing JavaScript for a while, you might be surprised to learn that setTimeout(0) is not really setTimeout(0). Instead, it could run 4 milliseconds later: const start = performance.now() setTimeout(() => { // Likely 4ms console.log(performance.now() - start) }, 0) Nearly a decade ago when I was on the Microsoft Edge team, it was explained to me that browsers did this to avoid “a
Introducing Zod Codecs
Zod 4.1 introduced a new z.codec() API for defining bi-directional transformations in Zod. The problem with transformsZod's .transform() method is great for one-way data conversion: const stringToNumber = z.string().transform(val => parseFloat(val)); stringToNumber.parse("42"); // 42But what if you need to go both ways? Say, you're storing dates as ISO strings in a database but want to work with D
How we made JSON.stringify more than twice as fast · V8
JSON.stringify is a core JavaScript function for serializing data. Its performance directly affects common operations across the web, from serializing data for a network request to saving data to localStorage. A faster JSON.stringify translates to quicker page interactions and more responsive applications. That’s why we’re excited to share that a recent engineering effort has made JSON.stringify i
Stop Re-Rendering — TanStack DB, the Embedded Client Database for TanStack Query | TanStack Blog
Stop Re-Rendering — TanStack DB, the Embedded Client Database for TanStack Query by Kyle Mathews and Sam Willis on Jul 30, 2025. Your React dashboard shouldn't grind to a halt just because one TODO turns from ☐ to ☑. Yet every optimistic update still kicks off a cascade of re-renders, filters, useMemos and spinner flashes. If you’ve ever muttered “why is this still so hard in 2025?”—same. TanStack
Introducing XMLUI
In the mid-1990s you could create useful software without being an ace coder. You had Visual Basic, you had a rich ecosystem of components, you could wire them together to create apps, standing on the shoulders of the coders who built those components. If you’re younger than 45 you may not know what that was like, nor realize web components have never worked the same way. The project we’re announc
How We Reduced CKEditor’s Bundle Size by 40% | CKEditor
In this article, we’ll show how we cut CKEditor 5’s bundle size by 40% through tree-shaking and bundle size optimization techniques and share tricks you can use to slim down your own JavaScript libraries. We’ll also walk through the tools and processes we used to achieve this, measure improvements, and catch regressions. As any software library author will tell you, building and maintaining is har

JavaScript scope hoisting is broken
7/6/2025 Most modern JavaScript bundlers implement an optimization called "scope hoisting". The idea is that rather than wrapping each bundled module in a function, a compiler concatenates the modules into a single scope. Say you have a program like this: // index.js import {add} from './math'; console.log(add(2, 3)); // math.js export function add(a, b) { return a + b; } When scope hoisted, the o
