The key: > immutable data structures --> "we are fully concurrent, because these are what I often call embarrassingly parallelizable problems" The relationship of their performance gains to functional programming ideas is explained beginning at 8:14 link to this video

…escript, Delphi & Turbo Pascal shows how a real engineer takes a decision of this magnitude. Is Go the best decision for every SW project? No, but in this case the arguments (and the tests they did during their evaluation) check out. And no, picking F# simply because you love the language is not a mature decision. You can check his arguments here: link to this video…

In the embedded video they show some of the code side by side and it is just a ton of if statements. link to this video

Not sure if it does but the video linked in the post might answer your question? I think he is compiling vscode which includes Monaco editor which is where they are getting 10x faster stat. (I might be wrong here.) 0 0 link to this video

Here's the FAQs, where they explain the decision to go with Go and not, say, rust. link Hejlsberg also says in this video, about 3.3x performance is from going native and the other 2-3x is by using multithreading. link to this video

On “New to Typescript, it's crazy slow...”

You're not (really) saying TypeScript is slow (although the TS compiler and toolset is built in TS); you're saying the TypeScript language server and/or linter is slow, which is a common complaint. This, in part, is why MS is porting TypeScript to Go. There are other ways to speed up the current TS language server. There's a few settings and tweaks you can make to your tsconfig (you'd need to look it up). You could switch to something like Biome, which is quite a bit faster. It's also a hardware matter. I'm on a 4-year-old ThinkPad, and the TS linter/language-server is pretty fast, even in large code-bases. Not INSTANT or PERFECT, but it's not horribly slow. If it's too slow for you, yo…
