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.
Python and Ruby are implemented in C, not interpreted languages
CoffeeScript simply compiles code and does not perform static analysis
tsc is implemented in JS and performs static analysis which makes it (unsurprisingly) slow
So again, use esbuild (go) or swc (rust) with type checking disabled if you want speed. Surprisingly, tsc doesn't have an option to disable type checking [1].
There is a js proposal to add this to language: https://github.com/tc39/proposal-pipeline-operator
There are few exceptions (namespaces, enums) but typescript has been quite averse to adding non-standard language level features outside type annotations. This feature will likely come to ts after this proposal has been accepted for js.
