@@can.getName()

The @@can.getName symbol points to a function that returns human-readable name of the object. Depending on the context this name could be decorated with extra information, like the cid of a given instance.

const foo = function() {};

foo[ canSymbol.for( "can.getName" ) ] = function() {
    return "MyFooFunction";
};

obj[ canSymbol.for( "can.getName" ) ](); //-> "MyFooFunction"
