Sort JSON file with NODEJS - arrays

Question

I just started using NodeJS (as of yesterday) I have managed to retrieve JSON data from an API as seen in the code below:
var request = require('request');
var fs = require('fs');
const pug = require('pug');
request.get('APICALL', function(err, data) {
if (err) { }
else {
console.log(data);
fs.writeFile('industries.txt', JSON.stringify(data));
}
});
The JSON data that my request.get returns can be found here JSON FILE
What I want to do is sort through this data, find out which revenue and industry ID appears the most (i.e for this data it's "revenue:8" and "industry:69") once this is done I want to return only companies who match both revenue 8 and industry 9.
Is this possible and what would be the best way to approach such a task?

Answer 1

You can count the revenue - industry_id occurences, sort descending and then filter by that:
let arr = [{"id":1,"domain":"google.com","alexa_rank":1,"country":236,"employees":"7","revenue":"8","industry_id":"69"},{"id":3,"domain":"youtube.com","alexa_rank":2,"country":236,"employees":"5","revenue":"8","industry_id":"69"},{"id":2,"domain":"facebook.com","alexa_rank":3,"country":236,"employees":"6","revenue":"8","industry_id":"69"},{"id":4,"domain":"yahoo.com","alexa_rank":6,"country":236,"employees":"6","revenue":"8","industry_id":"69"},{"id":111,"domain":"reddit.com","alexa_rank":9,"country":236,"employees":"3","revenue":"2","industry_id":"69"},{"id":9,"domain":"twitter.com","alexa_rank":12,"country":236,"employees":"5","revenue":"8","industry_id":"69"},{"id":230,"domain":"360.cn","alexa_rank":20,"country":46,"employees":"5","revenue":"8","industry_id":"69"},{"id":30,"domain":"weibo.com","alexa_rank":22,"country":46,"employees":"5","revenue":"2","industry_id":"69"},{"id":19,"domain":"google.de","alexa_rank":23,"country":236,"employees":"7","revenue":"8","industry_id":"65"},{"id":23,"domain":"google.co.uk","alexa_rank":24,"country":236,"employees":"7","revenue":"8","industry_id":"45"},{"id":12,"domain":"linkedin.com","alexa_rank":25,"country":236,"employees":"5","revenue":"8","industry_id":"69"},{"id":25,"domain":"google.fr","alexa_rank":26,"country":76,"employees":"1","revenue":"2","industry_id":"65"},{"id":46,"domain":"google.ru","alexa_rank":27,"country":236,"employees":"0","revenue":"8","industry_id":"69"},{"id":33,"domain":"google.com.br","alexa_rank":28,"country":32,"employees":"3","revenue":"3","industry_id":"47"},{"id":22,"domain":"yandex.ru","alexa_rank":29,"country":182,"employees":"5","revenue":"7","industry_id":"69"},{"id":20,"domain":"google.com.hk","alexa_rank":31,"country":46,"employees":"0","revenue":"8","industry_id":"69"},{"id":101,"domain":"netflix.com","alexa_rank":32,"country":236,"employees":"5","revenue":"8","industry_id":"38"},{"id":35,"domain":"google.it","alexa_rank":34,"country":236,"employees":"6","revenue":"8","industry_id":"113"},{"id":3351716,"domain":"ntd.tv","alexa_rank":36,"country":236,"employees":"4","revenue":"0","industry_id":"13"},{"id":77,"domain":"imgur.com","alexa_rank":37,"country":236,"employees":"3","revenue":"2","industry_id":"69"},{"id":21,"domain":"ebay.com","alexa_rank":38,"country":236,"employees":"6","revenue":"8","industry_id":"69"},{"id":41,"domain":"google.es","alexa_rank":39,"country":236,"employees":"1","revenue":"2","industry_id":"65"},{"id":74,"domain":"pornhub.com","alexa_rank":40,"country":58,"employees":"1","revenue":"3","industry_id":"38"},{"id":13,"domain":"msn.com","alexa_rank":41,"country":236,"employees":"8","revenue":"8","industry_id":"69"},{"id":18,"domain":"wordpress.com","alexa_rank":43,"country":236,"employees":"4","revenue":"3","industry_id":"69"},{"id":507,"domain":"aliexpress.com","alexa_rank":44,"country":46,"employees":"7","revenue":"8","industry_id":"69"},{"id":42,"domain":"livejasmin.com","alexa_rank":47,"country":128,"employees":"1","revenue":"0","industry_id":"38"},{"id":28,"domain":"microsoft.com","alexa_rank":48,"country":236,"employees":"8","revenue":"8","industry_id":"25"},{"id":58,"domain":"google.ca","alexa_rank":49,"country":236,"employees":"7","revenue":"8","industry_id":"69"},{"id":44,"domain":"tumblr.com","alexa_rank":50,"country":236,"employees":"4","revenue":"5","industry_id":"69"},{"id":107,"domain":"stackoverflow.com","alexa_rank":52,"country":236,"employees":"4","revenue":"3","industry_id":"69"},{"id":2553,"domain":"twitch.tv","alexa_rank":53,"country":236,"employees":"4","revenue":"4","industry_id":"69"},{"id":40,"domain":"imdb.com","alexa_rank":58,"country":236,"employees":"4","revenue":"3","industry_id":"69"},{"id":488,"domain":"github.com","alexa_rank":61,"country":236,"employees":"4","revenue":"5","industry_id":"25"},{"id":239,"domain":"pinterest.com","alexa_rank":62,"country":236,"employees":"4","revenue":"4","industry_id":"69"},{"id":1853,"domain":"popads.net","alexa_rank":65,"country":53,"employees":"1","revenue":"1","industry_id":"84"},{"id":51,"domain":"xvideos.com","alexa_rank":66,"country":59,"employees":"0","revenue":"0","industry_id":"38"},{"id":7154677,"domain":"diply.com","alexa_rank":68,"country":40,"employees":"3","revenue":"0","industry_id":"100"},{"id":245,"domain":"csdn.net","alexa_rank":69,"country":46,"employees":"3","revenue":"2","industry_id":"69"},{"id":189,"domain":"wikia.com","alexa_rank":72,"country":236,"employees":"4","revenue":"3","industry_id":"69"},{"id":275,"domain":"google.com.tw","alexa_rank":74,"country":218,"employees":"0","revenue":"8","industry_id":"95"},{"id":8456,"domain":"whatsapp.com","alexa_rank":75,"country":236,"employees":"3","revenue":"2","industry_id":"69"},{"id":56,"domain":"xhamster.com","alexa_rank":78,"country":58,"employees":"1","revenue":"0","industry_id":"38"},{"id":44705842,"domain":"txxx.com","alexa_rank":81,"country":0,"employees":"1","revenue":"0","industry_id":"38"},{"id":2793171,"domain":"coccoc.com","alexa_rank":84,"country":243,"employees":"3","revenu
