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.
But could we manage to achieve the same (avoid the same side-effect pollution), but entirely without handling it through the type system? Could we even manage to do it in JavaScript/TypeScript? Even without Haskell-ist wizardry like effect-ts?
Many languages merge the two concepts, and implement procedures as functions that return void. This may muddle/complect their distinction, causing programmers to call procedures from within functions, thereby making those functions into impure functions (meaning that they affect the world outside of themselves, through side-effects like I/O or mutating state). This should be avoided, especially if you care about debug-ability and Functional Core, Imperative Shell architectures (see Gary Bernhardt's Boundaries talk at 31:56) (which make testing your system easier, without mocking).
