Executing UPDATE statement with mysqljs

Im using mysqljs and I'm trying to UPDATE a table but it shows me an error with my SQL sentence.

the documentation states that 

connection.query('UPDATE users SET foo = ?, bar = ?, baz = ? WHERE id = ?', ['a', 'b', 'c', userId], function(err, results) {
  // ...
});

But when I try to do it, the query creates all the variables that I'm sending to the first ?, ignorign the other ones, like this

values = [1,2,3,4,5]
sql = 'UPDATE tablename SET col1= ?, col2 = ?, col3= ?, col4 = ? WHERE col5=  ?';

  var query = connection.query(sql, [values], function(err) {
      if (err) {
        console.log(err);
        throw err;
      }
      else {
        connection.end();
      }
  })

But the query that gets executes is:

UPDATE tablename SET col1= 1, 2, 3, 4, col2 = ?, col3= ?, col4 = ? WHERE col5=  ?';

I don't know what I'm doing wrong or what to do to fix it.

You aren't passing an array of values, you are passing an array of an array of values. Stop doing that.
