However, no type checking is performed and, [as Matt Pocock explains](https://x.com/mattpocockuk/status/1816524433106043331), experimental and TypeScript-only features are a no-no. Perhaps think of it as less _‘running TypeScript’_ and more _‘able to tolerate most of TypeScript’_?

A small-ish release, but Node 20 gains `process.getBuiltinModule` and `Blob#bytes`. Marco Ippolito 😍 Regarding last week's [issues with v20.5.0,](https://github.com/nodejs/node/pull/53934) the Node team has improved its testing processes to help avoid such problems in the future. No story to link to; I just follow [the Node team's livestreams](https://www.youtube.com/@nodejs-foundation/streams) and they were talking about it. :-) [How to Create Dockerfiles with Generative AI](https://www.docker.com/blog/how-to-create-dockerfiles-with-genai/) — The folks at Docker look at the potential for using ChatGPT to create Dockerfiles for Node projects.
