> Node had to create libraries from scratch and invent a ton of non-standard things along the way to do it. Deno is built on web standards but can also leverage many of the existing Node libraries by using std/node (the Node compatibility layer) or with jspm.io, for example Node.js is based on CommonJS [1] which defines the require() semantics for CommonJS/node.js modules as well as core libs/APIs such as JSGI (for express.js or node core http middleware) and others. When node.js was new, there were many JavaScript app server projects such as helma, v8cgi/TeaJS, and others, and CommonJS was very much a community effort.
