Using JSON escaping as a context we will explore:
- UTF-8, Unicode, and minimal implementation to support them (a.k.a. what you need to know but maybe don't);
- how to account for different implementations using
contexpr(considering performance).
Looking at JSON serialization/stringification we'll touch:
- ways to iterate over elements in JSON document with account for recursion;
- nuance of serializing floating point numbers;
- error reporting and nuances of exception types (in the context of serializing strings);
- serializing elements of unordered map in sorted order.
And a bit more.
