## Notes
As for [`BasicJsonType::size()`](https://json.nlohmann.me/api/basic_json/size/index.md), this does not return the length of a string value -- it is `1` for a string, regardless of its length.
As for [`BasicJsonType::size()`](https://json.nlohmann.me/api/basic_json/size/index.md), this does not return the length of a string value — it is `1` for a string, regardless of its length.
If the source text has an object with a duplicate key, every occurrence counts towards its `size()` -- unlike [`materialize()`](https://json.nlohmann.me/api/basic_json_view/materialize/index.md) (and [`BasicJsonType::parse()`](https://json.nlohmann.me/api/basic_json/parse/index.md)), which keeps only the last value for a repeated key. This means `v.size()` can be larger than `v.materialize().size()`. See the [Notes on duplicate keys](https://json.nlohmann.me/api/basic_json_view/operator%5B%5D/#notes) of `operator[]` for why lookups and iteration disagree on how many members there are.
