SurveyJS
Open-Source JSON Form Builder to Create Dynamic Forms Right in Your App. With SurveyJS form UI libraries, you can build and style forms in a fully-integrated drag & drop form builder, render them in your JS app, and store form submission data in any backend, inc. PHP, ASP.NET Core, and Node.js.
I picked the trivial example on purpose to make the point that none of the top 5 programming languages do it, even if it was solved in the 80s.
Recent languages like swift/kotlin (which I expect will see increased usage in coming years) seem to have ignored this area.

In poking around, I found this: https://github.com/microsoft/TypeScript/issues/14833
Where someone actually implements a compile-time check for prime numbers. I guess saying that it _can't_ be done is inaccurate. It's just absolutely horrendous.
