Javascript add objects to array

Question

In the code, im trying to add multiple objects into an array by using .push() method. All the objects are valid and type object when i log them using console.log but the array after the code runs is still empty.

Here's the code: app.js

const fs = require('fs');
var outdata = {};
var objArray = [];

fs.readFile('rawdata.json', 'utf8', (err, data) => {
  debugger;
  let dataObj = JSON.parse(data);             
  let tmpObj = {};
  Object.keys(dataObj).map(n => {
    let tmp = dataObj[n].search(/(\d{1,2}:\d{2}:\d{2})/g);
    if (tmp !== -1) {
      tmpObj = {};
      tmpObj.crafttime = dataObj[n];
      return true;
    } else {
      //make obj
      let value = dataObj[n].split(' ');
      tmpObj.type = value[0]; //type
      tmpObj.name = value[1].toLowerCase(); //name
      tmpObj.link = `abc.com/${value[1]}`;

      //appends obj
      objArray.push(tmpObj);
      return false; //break
    }
  });
});
console.log(objArray);

The console output expected :

[{obj},{obj},...]

output

[]

What is `tdolls.push(tmpObj);`? You want to push onto `objArray`. ` objArray.push(tmpObj);` — Jerinaw, May 26 '18 at 01:21

You have to put your console.log just one line above - in your fs.readFile callback - because it is asynchronous and the log is executed before the file is read.
