Node.js, MYSQL - how to get ONLY the data without column name

I'm using a select statement to pull the data from a mysql server:

client.query('SELECT attend FROM testnumbers WHERE Gym =2', function(err,result){
        var jay = result;
        console.log(jay);
});

When it returns 'jay', the result is this:

[ { attend: 455 } ]

I want ONLY the number to be in the variable 'jay'. How can I get rid of the other query stuff? Thanks!
