         | I mean, it's likely very important for them to have a fast and
         | sandboxed code executor available. But it's not like Bun would

         | specific areas, right?

         | If Bun breaks, Claude Code breaks. Anthropic has direct
         | incentive to keep Bun excellent.

         | Fast startup. Easy to distribute.

         | it set up in our internal Discord and we mostly use it to help
         | fix bugs. It opens PRs with tests that fail in the earlier
         | system-installed version of Bun before the fix and pass in the
         | fixed debug build of Bun. It responds to review comments. It
         | does the whole thing.

         | building the best JavaScript tooling.

           | we replaced Yarn Classic with Bun for package management and
           | replaced Bash scripts with Bun shell for setup and CI
