Use ?? to set value if something is NOT null

Learned to use the ?? operator when checking for null.  Use when you want something to = something else only when something else is not null:

var myvar = something_else ?? “default_value”;

myvar will be set to something_else only if something_else is not null, otherwise it will be “default_value” instead.
