TS Expert Challenge

Define a mapped type StringifyProperties<T> which maps all properties of type T to be of type string.

Write a function stringifyConfig(config) that takes an object, converts all of its property values to strings using String(), and returns the transformed object conforming to StringifyProperties<T>. Ensure you iterate through all owned keys of the input object.

Examples

stringifyConfig({ port: 80 })

→ { port: "80" }

stringifyConfig({ debug: true, val: 0 })

→ { debug: "true", val: "0" }
