Deno is a runtime for JavaScript and TypeScript that is based on the V8 JavaScript engine and the Rust programming language. It was announced by Ryan Dahl, the original creator of Node in 2018 and is actively discussed and disputed among developers. It’s not very likely that in the next several years Deno will replace Node.js, as the technology is still in the testing mode, developers try it and assess, get used to it. At the moment, there are not so many solutions on Deno, compared to Node.js. The Deno community is not a big one. On Stack Overflow - a community-based space to find and contribute answers to technical challenges - there are about 400 questions dedicated to Deno, which is not much, compared to node.js - 395,247. The differences in the implementation of features on Deno and Node.js are minimal. The support of developers is weak - there are not many developers using Deno and they have got limited experience due to not wide use of Deno.
