Should getDefaults be equivalent to v.parse (Schema, undefined)?

[wszgrcy]

import * as v from 'valibot';

(() => {
  const OptionalEntrySchema = v.optional(
    v.object({
      k1: v.optional(
        v.object({
          k2: v.optional(v.string(), 'value2'),
        }),
        {}
      ),
    }),
    {}
  );
  let b = v.parse(OptionalEntrySchema, undefined);
  console.log(b); // { k1: { k2: 'value2' } }
  console.log(v.getDefaults(OptionalEntrySchema)); //{}
})();

I think there should be a method to obtain the default value of a schema after parsing, so I used 'getDefaults'. However, this method can only obtain the default value of one layer of object and cannot recursively obtain it.
Should we add a separate function implementation or do we currently have no development plan for this?

Does this work for you? Here is a playground to execute the code.

import * as v from 'valibot';

const OptionalEntrySchema = v.object({
  k1: v.object({
    k2: v.optional(v.string(), 'value2'),
  }),
});

console.log(v.getDefaults(OptionalEntrySchema));

getDefaults will return any defined defaults, and if not, will recursively resolve defaults over objects and tuples. But right now it can't resolve optional objects without defaults because we can't know if the user wants it to return undefined or check for the wrapped schema and continue. This could be solved. It would be great to get more feedback on this. For now, you could also copy the source of getDefaults and modify it to your needs.
