How to use a repeat keyword in dialogflow?

Question

I am using actions-on-google and dialogflow to build a chatbot. The assistant asks the question and the user replies to it. Once the question has been asked and if the user says 'repeat' I want the question to be repeated. Is there any way I can do this? Here is my code:

app.intent('First', (conv) => {

    const rating = conv.parameters.any;
    senddata[0] = qstion[0] + rating;
    conv.ask(qstion[1]);
});

Can someone help me with this please?

Dialogflow has a concept of session storage which can store data only applicable to the session. In this way you can store data including your previous responses.

So it can be implemented as such:

app.intent('First', conv => {
    const rating = conv.parameters.any
    senddata[0] = `${qstion[0]}${rating}`
    conv.data.lastResponse = qstion[1]
    conv.ask(qstion[1])
})

app.intent('Repeat', conv => {
    if (conv.data.lastResponse) {
        conv.ask(`Here is what I said before: ${conv.data.lastResponse}`)
    } else {
        conv.ask(`I didn't say anything. Can you ask me something else?`)
    }
})
