在ArangoJS 3.x中使用NodeJs樣式函數回調

Question

是否有可能像使用函數回調一樣使用NodeJs與ArangoJs 3.x; 我看到，ArangoJs 3.x使用.then方法（承諾）.. 但我使用NodeJs 4.4 ..所以我不能使用.then方法..我可以使用nodejs像arangojs 3.x的函數回調嗎？

引述ArangoJS github page：

// ES2015-style 
import arangojs, {Database, aql} from 'arangojs'; 
let db1 = arangojs(); // convenience short-hand 
let db2 = new Database(); 
let {query, bindVars} = aql`RETURN ${Date.now()}`; 

// or plain old Node-style 
var arangojs = require('arangojs'); 
var db1 = arangojs(); 
var db2 = new arangojs.Database(); 
var aql = arangojs.aql(['RETURN ', ''], Date.now()); 
var query = aql.query; 
var bindVars = aql.bindVars; 

// Using a complex connection string with authentication 
let host = process.env.ARANGODB_HOST; 
let port = process.env.ARANGODB_PORT; 
let database = process.env.ARANGODB_DB; 
let username = process.env.ARANGODB_USERNAME; 
let password = process.env.ARANGODB_PASSWORD; 
let db = arangojs({ 
    url: `http://${username}:${password}@${host}:${port}`, 
    databaseName: database 
}); 

// Using ArangoDB 2.8 compatibility mode 
let db = arangojs({ 
    arangoVersion: 20800 
}); 

難道這不是正是你要找的東西？
