Deno (iːnoʊ/) is a runtime for JavaScript, TypeScript, and WebAssembly that is based on the V8 JavaScript engine and the Rust programming language. Deno was co-created by Ryan Dahl, the creator of Node.js, and Bert Belder.
Deno explicitly takes on the role of both runtime and package manager within a single executable, rather than requiring a separate package-management program.
Deno was announced at JSConf EU 2018 by Ryan Dahl in his talk "10 Things I Regret About Node.js". In his talk, Dahl mentioned his regrets about the initial design decisions with Node.js, focusing on his choices of not using promises in API design, usage of the legacy build system GYP, node_modules and package.json, leaving out file extensions, magical module resolution with index.js and breaking the sandboxed environment of V8. He eventually presented the prototype of Deno, aiming to achieve system call bindings through message passing with serialization tools such as Protocol Buffers, and to provide command line flags for access control.
