Can't Push Results to JavaScript Dictionary

Question

I am using google trends API to eventually export trends data to an excel file. The issue is I want to extract ONLY the formattedTime and value for my keywords. While Ive tried to do this, I've also noticed that results are not being pulled properly. For instance, when I try to push results from the API to an empty dictionary, I continue to get an empty array.

Any idea?

Thank you.

'use strict';

const googleTrends = require('google-trends-api');

var something = [];    

    googleTrends.interestOverTime({
        keyword: 'animals',
        startTime: new Date(Date.now() - (1 * 60 * 60 * 1000)),
        granularTimeResolution: true,
    }, function(err, results) {
        something.push(results);
        if (err)
            console.log('oh no error!', err);
        else
            console.log("--------------------------")

    });

console.log(something);

Example of Data Pulled:

{
  "default": {
     "timelineData":[
       {
         "time":"1511629200",
         "formattedTime":"Nov 25, 2017 at 12:00 PM",
         "formattedAxisTime":"Nov 25 at 12:00 PM",
         "value":[44],
         "formattedValue":["44"]
       },
       {
         "time":"1511632800",
         "formattedTime":"Nov 25, 2017 at 1:00 PM",
         "formattedAxisTime":"Nov 25 at 1:00 PM",
         "value":[41],
         "formattedValue":["41"]
       }
     }]
   }
}

Your call to Google is asynchronous, so you need to log out your results inside the callback where you push the results into something. Otherwise your console.log(something) is actually running before your callback completes, and no values have yet been pushed into your array.

'use strict';

const googleTrends = require('google-trends-api');

var something = [];    

googleTrends.interestOverTime({
    keyword: 'bitcoin',
    startTime: new Date(Date.now() - (1 * 60 * 60 * 1000)),
    granularTimeResolution: true,
}, function(err, results) {
    something.push(results);
    if (err)
        console.log('oh no error!', err);
    else{
        console.log(something);
        console.log("--------------------------")
    }
});
