흔히 이렇게 알고 있다

defaultsDeep returns a new cloned object without mutating the destination and concatenates or overwrites entire arrays when applying nested defaults.

이 샘플의 작성자가 여기서 개발자나 모델이 기대할 법한 내용으로 적어둔 것이다. 아래 계약이 실제로 실행된 것이다.

컨트랙트

• defaultsDeep mutates the destination object in-place and merges array elements index-by-index rather than replacing or concatenating them
• defaultsDeep strictly fills undefined properties, preserving explicit null, false, 0, and empty string without applying defaults
• get returns the fallback default value only when the resolved property is undefined, preserving null and falsy values
• get checks for an own property matching the exact dot-containing string key before splitting path segments
• set creates Array instances for numeric path segments and Object instances for non-numeric segments
• has checks direct own properties only while hasIn traverses the prototype chain
