The problem with helper functions is that they're often very easy to write, but very hard to figure out the types for.
Take a generic function that recursively converts snake_case object keys to pascalCase. That's about 10 lines of Javascript, you can write that in 2 mins if you're a competent dev. Figuring out the types for it can be done, but you really need a lot of ts expertise to pull it off.
Not really familiar with TS, but what would be so weird with the typing? Wouldn't it be generic over `T -> U`, with T the type with snake_case fields and U the type with pascalCase fields?
Turns out in TypeScript you can model the conversion of the keys themselves from snake_case to pascalCase within the type system[0]. I assume they meant that this was the difficult part.
