Ryan Dahl is the co-founder and creator of Deno, a runtime for JavaScript, TypeScript, and WebAssembly based on the V8 JavaScript engine and the Rust programming language. He is also the creator of Node.js. We interviewed Dahl for The New Stack Technical Founder Odyssey series. "Yeah, so we have a JavaScript runtime," Dahl said. "It's pretty similar in, in essence, to Node. It executes some JavaScript, but it's much more modern. " The Deno project started four years ago, Dahl said.
