한 함수에서 Node.js의 다른 함수로 변수를 전달하는 방법은 무엇입니까?

Question

topic_to_learn 변수를 두 번째 함수에 전달하고 두 번째 함수에서 다른 변수에 사용하려고합니다.

function (session, args, next) { 
     var topic_to_learn = builder.EntityRecognizer.findEntity(args.entities, 'topic_to_learn'); 
     builder.Prompts.text(session, 'Sure, can you please also tell me about your goals or anything you want to achieve after learning about this topic?'); 
    }, 
    function (session, results, next) { 
     var learning_goals = results.response; 
     session.send('Got it, let me think...', session.message.text); 
     session.send('Voila! These are the articles related to ' + topic_to_learn, session.message.text); 
    }, 

Answer 1

두 가지 기능 모두에서 사용할 수있는 위의 범위 변수를 사용할 수 있습니다.

var topic_to_learn; 

    function (session, args, next) { 
     topic_to_learn = builder.EntityRecognizer.findEntity(args.entities, 'topic_to_learn'); 
     builder.Prompts.text(session, 'Sure, can you please also tell me about your goals or anything you want to achieve after learning about this topic?'); 
    }; 

    function (session, results, next) { 
     var learning_goals = results.response; 
     session.send('Got it, let me think...', session.message.text); 
     session.send('Voila! These are the articles related to ' + topic_to_learn, session.message.text); 
    }, 

Answer 2

.matches('get_learning_plan', [ 

     function (session, args, next) { 
      var topic_to_learn = builder.EntityRecognizer.findEntity(args.entities, 'topic_to_learn'); 
      builder.Prompts.text(session, 'Sure, can you please also tell me about your goals or anything you want to achieve after learning about this topic?'); 
     }, 
     function (session, results, next) { 
      var learning_goals = results.response; 
      session.send('Got it, let me think...', session.message.text); 
      session.send('Voila! These are the articles related to ' + topic_to_learn, session.message.text); 
     },
