I'm designing a trivia game in Dialogflow, how can I keep the score?

In the fullfilments in Dialogflow, you can use the context to serve as a memory for keeping the score. Here is a code example that increases, resets or returns the score depending on the selected intent.

'use strict';
  
const functions = require('firebase-functions');
const {WebhookClient} = require('dialogflow-fulfillment');
const {Card, Suggestion} = require('dialogflow-fulfillment');

process.env.DEBUG = 'dialogflow:debug'; // enables lib debugging statements

exports.dialogflowFirebaseFulfillment = functions.https.onRequest((request, response) => {
const agent = new WebhookClient({ request, response });
console.log('Dialogflow Request headers: ' + JSON.stringify(request.headers));
console.log('Dialogflow Request body: ' + JSON.stringify(request.body));

function reset(agent) {   
    agent.setContext({
    name: 'score',
    lifespan: 20,  // Amount of follow-up intents this context will be kept
    parameters: {'score': 0},
    });
    
    agent.add(`tu veux gagner un point?`);
}

function get_score(agent) {    
    const score_context = agent.getContext('score');
    let score_value = score_context.parameters.score;
    
    agent.add(`Le score final est de ` + score_value);
}

function good_answer(agent) {    
    const score_context = agent.getContext('score');
    const score_value = score_context.parameters.score + 1;
    
    agent.setContext({
    name: 'score',
    lifespan: 20,  // Amount of follow-up intents this context will be kept
    parameters: {'score': score_value},
    });
    
    agent.add(`j'ajoute un, le nouveau score est de ` + score_value);
}

function wrong_answer(agent) {
    const score_context = agent.getContext('score');
    let score_value = score_context.parameters.score;
    //not adding anything
    
    agent.setContext({
    name: 'score',
    lifespan: 20,  // Amount of follow-up intents this context will be kept
    parameters: {'score': score_value},
    });
    
    agent.add(`dommage!`);
}

// Run the proper function handler based on the matched Dialogflow intent name
let intentMap = new Map();
intentMap.set('premiere question', reset);
intentMap.set('premiere question - yes', good_answer);
intentMap.set('premiere question - no', wrong_answer);
intentMap.set('score final', get_score);
// intentMap.set('your intent name here', yourFunctionHandler);
// intentMap.set('your intent name here', googleAssistantHandler);
agent.handleRequest(intentMap);
});
