To get a JSON string (e.g., from reading a file) into an actual JavaScript object, use JSON.parse(string). Here is an example:
fs.readFile('data.txt', function(err, data) {
if (err) throw err;
var array = JSON.parse(data); // converts the JSON string into an actual object/array
// use array as you did in your question...
});
BONUS: Use a for...of loop to process each element of the array:
for (var obj of array) {
console.log(obj.date_created);
// etc.
}
Note that this is only available since ECMAScript 6, but since you're using Node.js, that shouldn't be a problem.

This file contains a VALID JSON STRING, so just read the file and do JSON.parse(), and then you can do anything else with the JSON object.
