Ryan Dahl (born 1981) is an American software engineer and the original developer of the Node.js JavaScript runtime and the Deno JavaScript and TypeScript runtime.[1][2][3]

Early life and education[edit]

Dahl grew up in San Diego, California. His mother got him an Apple IIc when he was six years old, one of his first experiences with technology. Ryan attended a community college in San Diego and later transferred into UC San Diego where he studied mathematics. He went on to attend grad school for Mathematics at the University of Rochester where he studied algebraic topology, which he found "very abstract and beautiful" for a couple of years but later got bored of it because "it was not so applicable to real life."


After working on the Node project since 2009, Dahl announced in January, 2012 that he would step away from the project and turn over the reins to NPM creator and former Joyent employee Isaac Z. Schlueter.[4][5]

Ryan Dahl gave the following reason for moving on from the project:

“After three years of working on Node, this frees me up to work on research projects. I am still an employee at Joyent and will advise from the sidelines but I won’t be involved in the day-to-day bug fixes.”[6]

In 2018 he announced Deno, a JavaScript/TypeScript runtime built with V8.[7]
