JavaScript survey reveals gripes against date handling, Webpack and Next.js - and that "TypeScript has won"

The 2025 State of JavaScript survey (~12,000 respondents) highlights key developer sentiments: 40% code exclusively in TypeScript and that share is growing, prompting the conclusion that 'TypeScript has won.' Top pain points include lack of static typing and poor date handling, though the TC39 Temporal proposal now ships in Chrome 144. Webpack remains widely used (86%) but is disliked by 37% for complexity and slowness, while Vite enjoys near-equal usage with far higher satisfaction. Next.js faces criticism for growing complexity and perceived over-reliance on Vercel. Bun is rising as a runtime (21% usage), Cloudflare Workers grew from 1% to 12%, and Node.js remains dominant at 90%. The survey's conclusion recommends adopting the Vite toolchain, including Vitest, in 2026.
