We bet big on deno with Windmill (OSS platform to turn scripts into internal UI and workflows) [1][2] and are extremely pleased. The language design choices and the performances/caching strategies are a perfect match for building a distributed workflow runtime at scale. However, the compatibility with npm was the most requested feature. Before the compatibility mode with npm was released, we were about to build a completely separate mode of execution based on node. This solves it very elegantly.
Also super excited about the lsp improvements. I believe we are the only project to have a webeditor that features lsp integration with deno in the web (to test, go on [3], New Script -> Next, it works really well). It's very pleasant to work with and make the webeditor experience match closely a local dev setup. We are super excited about the improvements and I am about to try tonight if we can have the inline hints work with monaco. As we are fully open-source, one can see how we are able to pull it off [4][5].
