NativeScript looks interesting and would be where I reached if React/RN TypeScript wasn't my preference.

React Native has a much larger ecosystem and feature set, including desktop & web targets, native view, many extensions, huge support, a lot of jobs.

NativeScript seems to just tie into native APIs, not the view layer, right? React Native bridges to native controls so you get native look and feel.

Flutter emulates the native view later by drawing everything itself which can be off, but it's performant at least.

If I preferred Web components, Svelte, Angular, or Vue I'd see the appeal of NativeScript.
