object: T
): FlattenDotValue<MergeAll<[T]>>Parameters
object(T): The nested object to flatten.
Return Value
FlattenDotValue<MergeAll<[T]>>: A flat object with dot-notation keys mapped to their original nested values.

Date,RegExp, etc. are preserved as-is. - Returns a new object without mutating the original
