Deno is a new runtime for Javascript and Typescript created by Ryan Dahl – the original creator of Node.js. In his famous talk “10 Things I Regret About Node.js” given in 2018 he listed some of the Node.js design mistakes. Deno is supposed to fix these problems. Through this talk I will show you the core features of Deno and compare it with Node.js, using code examples. Then I will try to answer the talk title question together with the attendees.
