JSON to TypeScript: questions
Does it handle arrays of mixed types?
It generates a union type for the array element type. If all objects share the same shape, you get a clean single interface.
How are keys with special characters handled?
Keys that aren't valid TypeScript identifiers are wrapped in quotes in the interface definition.
