Description

JsonVariant::getMember() gets the value associated with the specified key; it reproduces JsonObject::getMember().

If the JsonVariant points to an object, this function returns a JsonVariant pointing to the specified member.

If the JsonVariant does not point to an object, this function returns a null JsonVariant.

Instead of this function, you can use JsonVariant::operator[] which offers a more intuitive syntax.
