> that's rare, but great Not OP. At a big tech company. As far as I can tell neither myself nor anyone I work with has touched a system developed in the past 6 years that didn't use React with with Webpack and/or Esbuild for the build system. Of those, 90% + used Redux for state management or switched to Redux after starting with a different state management system like mobx or xstate. The only exception to this the only exceptions are apps that needed something Recoil-like (e.g. Redux caused too much computational overhead). Some of them also used Nextjs for static pages.
