>Ryan Dahl left the leadership of the Node.js pretty early in its development. A lot of people can be considered "the creator" of Node.js to be fair.
Don't think so. I have been using Node.js since 2010 and following the ecosystem. Node.js is the child of Ryan Dahl. Other than Ryan, perhaps Isaac Schlueter is the most influential person who developed the NPM as a separate project and later merged into Node. Ryan could have done it himself or embedded it in Node.js, but guessing from Deno he is not keen on a centralised package repository so could have let Isaac build NPM as a separate project.
From what I could observe, the overall API is still pretty much the same from 2010. What's changed is V8 getting updated to newer versions (and thereby supporting new ES features) and other performance optimizations. But no one can't deny or take away the creator credit from Ryan.
