Bun Rewritten in Rust: Speed Gets an Upgrade

Remember Bun? That blazing-fast JavaScript runtime that aimed to replace Node.js and Deno, but was written in Zig? Well, it just underwent a major change: the pull request rewriting Bun in Rust has been merged. Yes, you read that right.

On one hand, this feels like moving to a new apartment and deciding to repaint the walls, replace the plumbing, and refinish the floor all at once. On the other hand, the Bun team clearly knows what they're doing. Rust is famous for memory safety and performance, so this might not be just a "reshuffle" but a genuine upgrade.

Of course, this doesn't mean Bun will stop supporting JavaScript and TypeScript. It's more like swapping the engine in a sports car without changing the body. The internals become more reliable, while the exterior stays familiar. The question is: will this follow the fate of projects rewritten in Rust just because it's trendy? Only time will tell.

For developers, this means a potentially more stable and faster tool. If you're already using Bun in CI, get ready for even quicker builds. If not, maybe now's the time to give it a spin. Just remember to update your local version, or your colleague who follows the news will mock your outdated binary.

Studio METABYTE comment: Rewriting in Rust is like renovating during a deadline — scary but potentially awesome. We're all for optimization, but we recommend testing on a side project first to avoid a "blue screen" in production.
