json - how to get key value pair from body object in javascript while using request module -


i creating application in want use data json, generated js file. here code generating json

var request = require('request');    module.exports = {  foo:  request('https://westus.api.cognitive.microsoft.com/luis/v2.0/apps/c1d1e5d6-fe5c-42de-8713-60f272a3b63e?subscription-key=d3d3e4dfa8744be9b4ae47558df8fc5a&timezoneoffset=0&verbose=true&q=hey',function (error, response, body) {    console.log('error:', error); // print error if 1 occurred     console.log('statuscode:', response && response.statuscode); // print response status code if response received     console.log(body);  })  };

i interested in body object, giving following contents -

{    "query": "hey",    "topscoringintent": {      "intent": "help",      "score": 0.500165462    },    "intents": [      {        "intent": "help",        "score": 0.500165462      },      {        "intent": "none",        "score": 0.10364107      },      {        "intent": "searchhotels",        "score": 0.00249445555      },      {        "intent": "showhotelsreviews",        "score": 9.451727e-06      }    ],    "entities": []  }

now want access value of intent topscoringintent element. in js file. tried using body[1].intend gives undefined. new javascript , need basic code this. please give suggestions on this. plz tell me if can solved body-parser , if yes how?

update - here code want use body['topscoringintent'].intent global. 

require('dotenv-extended').load();    var builder = require('botbuilder');  var restify = require('restify');  var store = require('./store');  var spellservice = require('./spell-service');  var request = require('request');  var myjson = require("json");  var fs = require('fs');  //var window = window;  var request = require("request");  var myjson = require("json");    var globalvar = [];    // setup restify server  var server = restify.createserver();    server.listen(process.env.port || process.env.port || 3978, function () {      console.log('%s listening %s', server.name, server.url);  });  // create connector , listen messages  var connector = new builder.chatconnector({      appid: process.env.microsoft_app_id,      apppassword: process.env.microsoft_app_password  });  server.post('/api/messages', connector.listen());        function getmybody(url, callback) {    request({      url: 'https://westus.api.cognitive.microsoft.com/luis/v2.0/apps/c1d1e5d6-fe5c-42de-8713-60f272a3b63e?subscription-key=d3d3e4dfa8744be9b4ae47558df8fc5a&timezoneoffset=0&verbose=true&q=hey',      json: true    }, function (error, response, body) {      if (error || response.statuscode !== 200) {        return callback(error || {statuscode: response.statuscode});      }        global.topscoringintent = body['topscoringintent'].intent;      //if(body['topscoringintent'].intent == 'help');      //console.log('yay');      callback(null, body);      });    }    getmybody('https://westus.api.cognitive.microsoft.com/luis/v2.0/apps/c1d1e5d6-fe5c-42de-8713-60f272a3b63e?subscription-key=d3d3e4dfa8744be9b4ae47558df8fc5a&timezoneoffset=0&verbose=true&q=hey', function(err, body) {    if (err) {      console.log(err);    }   })    if(body['topscoringintent'].intent == 'help');      console.log('success');

this should work you

console.log(response.topscoringintent.intent);

recursion - Can every recursive algorithm be improved with dynamic programming? -

i first year undergraduate csc student looking competitive programming. recursion involves defining , solving sub problems. understand, top down dynamic programming (dp) involves memoizing solutions sub problems reduce time complexity of algorithm. can top down dp used improve efficiency of every recursive algorithm overlapping sub problems? dp fail work , how can identify this? the short answer is: yes. however, there constraints. obvious 1 recursive calls must overlap. i.e. during execution of algorithm, recursive function must called multiple times same parameters. lets truncate recursion tree memoization. can use memoization reduce number of calls. however, reduction of calls comes price. need store results somewhere. next obvious constraint need have enough memory. comes not-so obvious constraint. memory access requires time. first need find result stored , maybe copy location. in cases, might faster let recursion calculate result instead of loading somewher...
