Discussion - Topic: React JS

This week's topic: React JS

Discussion resources to help guide the conversation will be posted below a few days before the meetup.

Zoom link will be added about 5 min before the event starts.

As described in Thoughtworks Technology Radar Vol. #34.

React has been our default choice for JavaScript UI development since 2016, but with the stable release of React Compiler coming last October (as part of React 19), it’s worth revisiting. There are a number of reasons this feature is notable. By handling memoization at build time, for example, it makes manual useMemo and useCallback largely unnecessary, though the team recommends keeping them as escape hatches when precise control over effect dependencies is required. Battle-tested at Meta and supported by Expo SDK 54, Vite and Next.js, the compiler also removes a category of performance boilerplate that has long been a cost of working at scale with React. React 19 also introduces Actions and hooks such as useActionState and useOptimistic, which simplify form handling and data mutations without relying on external libraries. The launch of the React Foundation under the Linux Foundation in 2025 — with Amazon, Expo, Callstack, Microsoft, Software Mansion and Vercel joining Meta — further strengthens the library’s long-term stability and addresses a concern cautious teams have historically cited when considering adoption.
