Function defaultsDeep

defaultsDeep<A extends object>(a?: Partial<A>): A
Perform a deep defaults‑style merge across plain objects.
- Only merges plain objects (prototype === Object.prototype).
- Arrays and non‑objects are replaced, not merged.
- undefined values are ignored and do not overwrite prior values.
Type Parameters
- A extends object
Parameters
- Optionala: Partial<A>
Returns A
The merged object typed as T.
Example
```
defaultsDeep({ a: 1, nested: { b: 2 } }, { nested: { b: 3, c: 4 } })
=\> { a: 1, nested: { b: 3, c: 4 } }
```
