如何在函数JS + Cypher中访问值

Question

This is a query with de Neo4j js driver. The query works fine, and I can get the value in the var x . But the value only can be access inside the function g. If I try to call the function I have a message that said that g is no defined. (thank you for your help)

session
    .run( "MATCH (a:Autor) RETURN a.nombre AS name") 
    .then( 
        function g( result ) { 
            var x=result.records[0].get("name");//ok, x take the value
            console.log('es '+x); //ok, print the first value of the db
            session.close();
            return x;
        });
var r=g(); //error Uncaught ReferenceError: g is not defined
console.log('es '+r); //do not execute this part

try this :

var result = session
.run( "MATCH (a:Autor) RETURN a.nombre AS name") 
.then( 
    function g( result ) { 
        var x=result.records[0].get("name");//ok, x take the value
        console.log('es '+x); //ok, print the first value of the db
        session.close();
        return x;
    });

Now to get the result anywhere, simply do this :

result.then( function (data) { console.log('es' + data) });
