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.
Parameters
other
(in)- value to copy from
Complexity

Example
??? 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"
```
