Language runtimes compared: Node.js, Deno and Bun, how they execute code and which to pick.
A production deep dive into Bun v1.3.11 — covering Bun.cron for OS-level scheduling, Bun.sliceAnsi for terminal-aware string slicing, enriched Markdown rendering callbacks, path-ignore patterns for test discovery, and the dgram UDP fixes that unblocked real-world libraries on macOS.
Three JavaScript runtimes. Three different philosophies on what the developer experience should feel like. Here's how they compare on performance, ecosystem, tooling, and the only decision that actually matters for production.
Bun is a JavaScript runtime, package manager, bundler, and test runner in a single binary written in Zig. It's also the fastest thing to happen to JavaScript tooling in years — and it runs your existing Node.js code.
In 2018, Ryan Dahl stood at JSConf EU and apologized for Node.js. Then he built Deno to fix the things he got wrong. Here's what changed, what the security model actually looks like, and whether switching is worth it.
