"We intend for Bun to be a drop-in replacement for the existing ecosystem. Most of our engineering time is not actually spent on new features — it's spent on compatibility". Join our conversation with Jarred Sumner, creator of Bun — a fast, all-in-one toolkit for installing, bundling, running, and testing JavaScript & TypeScript. Previously, he was a frontend engineer at Stripe. The host is Patrick Akil, Beyond Coding podcast host. In this conversation with Jarred, we explore the story behind Bun — why it was created, how adoption is going, and what makes it exciting. Jarred also talks about compatibility with , upcoming features, how AI is shaping developer workflows today — and more!
