When Alternative JS Runtimes Grow Up: Deno Has Big Changes Ahead, and the Creator of Bun Forms Oven

Two distinct stories that we felt deserved to be together as they provide a little look at the development of alternative server-side JavaScript runtimes that aren’t Node.js and are both going after overlapping markets.

Deno’s big news is that they’re working hard on npm compatibility and Deno will be able to use most npm modules soon (Deno 1.25 has been released with a preview). Meanwhile, Jarred Sumner, the creator of Bun, has answered our pun prayers and formed Oven, a company to support Bun’s development, and already raised $7m for it. The heat is, most certainly, on.
