PERTAIN_TOProblem

I tried using `[key in FormData]:string`, but that forces me to have all fields, and not just one. Tension: I want to create a type that could encase the following: `{field1: string}` or `{field2: string}` and all other potential fields. Outcome: I don't want to make them all ignorable with `?`.

PERTAIN_TOSolution

You can use Typescript Mapped Types and declare a type like this — Since you want at least one key.
