Copy assignment operator. Copies a JSON value via the “copy and swap” strategy: It is expressed in terms of the copy constructor, destructor, and the swap()
member function.

??? example
The code below shows and example for the copy assignment. It creates a copy of value `a` which is then swapped with `b`. Finally, the copy of `a` (which is the null value after the swap) is destroyed. ```cpp --8<-- "examples/basic_json__copyassignment.cpp" ``` Output: ```json --8<-- "examples/basic_json__copyassignment.output" ```
