Understanding the application of JSON data can be simplified by following these

I am looking to manipulate dates by either adding or subtracting them, but I am unsure of how to extract the dates from the other data present.

var fetch = require('node-fetch');

fetch('https://api.nasa.gov/planetary/earth/assets?lon=100.75&lat=1.5&begin=2014-02-01&api_key=DEMO_KEY')
  .then(response => response.json())
  .then(data => console.log(data));

This is the current output I am receiving:

{
   count:56,
   results:[
      {
         date:'2014-02-04T03:30:01',
         id:'LC8_L1T_TOA/LC81270592014035LGN00'
      },
      {
         date:'2014-02-20T03:29:47',
         id:'LC8_L1T_TOA/LC81270592014051LGN00'
      },
      {
         date:'2014-03-08T03:29:33',
         id:'LC8_L1T_TOA/LC81270592014067LGN00'
      },
      {
         date:'2014-03-24T03:29:20',
         id:'LC8_L1T_TOA/LC81270592014083LGN00'
      }
    ]
}

JavaScript :

var dateList = new Array();
var jsonData = {
   totalEntries:56,
   entries:[
      {
         entryDate:'2014-02-04T03:30:01',
         entryID:'LC8_L1T_TOA/LC81270592014035LGN00'

      }
    ]
};
var temporaryData = jsonData.entries;
for(var index= 0; index<temporaryData.length;index++){
    dateList.push(temporaryData[index].entryDate);
}
console.log(dateList);

Answer №5

When performing addition or subtraction on dates, it is necessary to first convert the date received as a string into a Date object.

var allDates = [];
var request = require('request');
request('https://api.example.com/data?lon=100.75&lat=1.5&date=2022-10-15&api_key=API_KEY', function (error, response, body) {
  var data = JSON.parse(body);

  var results = data.results;
  for(var i=0; i<results.length; i++) {
   allDates.push(new Date(results[i].date)); // Storing dates as Date objects in an array
   // Perform your operations here using (new Date(results[i].date))
  }
});
