How to filter json in javascript?

Question

Ok, so my code retrieves json from a websocket and currently prints all the json to console. What I want to do is store pieces of information as variables. How can I turn:

{
    "type": "question",
    "ts": "2018-06-30T00:05:53.685Z",
    "totalTimeMs": 10000,
    "timeLeftMs": 10000,
    "questionId": 46220,
    "question": "In wrestling, what term refers to pretending that scripted theatrics are totally real?",
    "category": "Entertainment",
    "answers": [{
            "answerId": 140757,
            "text": "Gas"
        },
        {
            "answerId": 140758,
            "text": "Kayfabe"
        },
        {
            "answerId": 140759,
            "text": "House show"
        }
    ]

Into:

    Question = In wrestling, what term refers to pretending that scripted theatrics are totally real?
pAnswer1 = Gas
pAnswer2 = Kayfabe
pAnswer3 = House show

I'm using node.

This provides what you want. Click "Run code snippet" below to see the output.

const obj = {
 "type": "question",
 "ts": "2018-06-30T00:05:53.685Z",
 "totalTimeMs": 10000,
 "timeLeftMs": 10000,
 "questionId": 46220,
 "question": "In wrestling, what term refers to pretending that scripted theatrics are totally real?",
 "category": "Entertainment",
 "answers": [{
  "answerId": 140757,
  "text": "Gas"
 }, {
  "answerId": 140758,
  "text": "Kayfabe"
 }, {
  "answerId": 140759,
  "text": "House show"
 }]
}

const question = obj.question;
const pAnswer = obj.answers.map(ans => ans.text);

console.log('question =', question);
pAnswer.forEach((ans, i) => {
  console.log(`answer${i+1} =`, ans);    
})
