Summary:
There are two implementations of `RCTConvertVecToArray`. The first implementation:
```
template<typename ContainerT>
NSArray *RCTConvertVecToArray(const ContainerT &vec, id (^convertor)(typename ContainerT::value_type element))
{
NSMutableArray *array = [NSMutableArray new];
for (size_t i = 0, size = vec.size(); i < size; ++i) {
id object = convertor(vec[i]);
array[i] = object ?: (id)kCFNull;
}
return array;
}
```
The purpose of the second implementation is to default the convertor function to the identify function:
```
template<typename ContainerT>
NSArray *RCTConvertVecToArray(const ContainerT &vec)
{
return RCTConvertVecToArray(vec, ^id(typename ContainerT::value_type element) { return element; });
}
```
Meanwhile, there's only one implementation of `RCTConvertOptionalVecToArray`:
```
template<typename ContainerT>
NSArray *RCTConvertOptionalVecToArray(const folly::Optional<ContainerT> &vec, id (^convertor)(typename ContainerT::value_type element))
{
return vec.hasValue() ? RCTConvertVecToArray(vec.value(), convertor) : nil;
}
```
In this diff, I overload `RCTConvertOptionalVecToArray` to default the convertor to the identify function.
