This is probably written by someone who works with C# much more than with Typescript. There's nothing here about narrowing, (proper) type inference, union and intersection types etc... When I tried C#, coming from Typescript, I was frequently hitting limitations that made sense from a historical perspective, but were killing elegant solutions. For example, C# has null-safety, but it's different for Value-Types than for Reference-Types. So you can't have a generic function over Optional<T>. Tbf, I was using Unity, which adds its own layer of insanity. And, as with any language, you eventually learn to work around the limitations. But presenting both languages as interchangeable is naive.
