:mrdocs:

Return a theoretical upper bound on the largest number of elements that this `JsonArray` could possibly hold. Requests to create a `JsonArray` longer than this number of elements are guaranteed to raise a `bsl::length_error` exception. Note that there is no guarantee that the `JsonArray` can successfully grow to the returned size, or even close to that size, without running out of resources.
