This stuff pre-dates .NET and quite honestly I think that’s what m$ was going for in those early days. VBScript was pretty annoying and dealing with COM objects sucked badly. Back in the day we’d build in a local VB interop with JavaScript so we could make system calls and interact with native Windows stuffs. This predates JSON so at the time we’d use XmlHttpRpc to talk to remote/hosted services.

I’ll double down on the urge to drop TypeScript. That pile of nonsense came from the classic OOP folks - “But where are my TYPEs!? How do I know what type that variable is!?” (first the Java/C++ folks then the .NET folks “solved” the brain fuzz around functional programming and dynamic types by giving you TypeScript)

Having been out of the m$ ecosystem for some time, I’m kinda surprised HTAs are still around, I’m guessing to avoid breaking things. Once .NET started taking off - I always assumed that would replace the VBScript side of things and let you build proper, elegant system interfaces for your JavaScript app. I really imagined the goal was to drop Windows forms/object controls - but I always imagined BATTLES at m$ over being able to create Windows “apps” that didn’t conform to native UI controls, couldn’t be controlled through Windows theming engines, etc. kinduva brand control battle. I always imagined some team going “NOOO, just build a web app, you’re breaking all the UI rules!!!”
