Tests:

Reduce (reuse object)
const getReuseObject = (object) => Object.keys(object).reduce( (obj, key) => ({ ...obj, [key]: Object.keys(object[key]).reduce( (obj1, key1) => ({ ...obj1, [key1]: object[key][key1].defaultValue, }), {}, ), }), {}, ); getReuseObject(bigObject)
Reduce (creating temporary objects)
const getTemporaryObject = (object) => Object.keys(object).reduce((obj, key) => { const newObj = { ...obj }; const object1 = object[key]; newObj[key] = Object.keys(object1).reduce((obj1, key1) => { const newObj1 = { ...obj1 }; newObj1[key1] = object1[key1].defaultValue; return newObj1; }, {}); return newObj; }, {}); getTemporaryObject(bigObject)
