How do add comma between two json objects when saving them into a text file?

See more:

when saving an array of objects as a JSON, you need to use the following format in Sample.txt to not run into parsing errors:

[{"result":"\"21 inches = 21 inches\"","count":1},{"result":"\"32 inches = 32 inches\"","count":2}]

I'm new to JSON and searching over this for since last 4 days. I tried different approaches of storing an array of objects but no success. My first and simplest try is like this:

JavaScript

function createData() {
    //original, single json object
    var dataToSave = {"result": '"' + toLength.innerText +'"', //taking value from DOM
            "count":  counter       //counter = counter + 1;
    };

     //save into an array:
     var dataArray = { [] };    //No idea how to go ahead.. 


     var savedData = JSON.stringify(dataToSave);    
     writeToFile(filename, savedData);  //filename is a text file. Inside file, I want to save each json object with , in between. So It can be parsed easily and correctly.

}
function readData(data) {
    var dataToRead = JSON.parse(data);

     var message = "Your Saved Conversions : ";

     message += dataToRead.result;

     document.getElementById("savedOutput1").innerText = message;
}

Hello,

This is how you will do this.

JavaScript

function createData() {
    //original, single json object
    var dataToSave = {"result": '"' + toLength.innerText +'"', "count":  counter};
 
     //save into an array:
     var dataArray = new Array();    //No idea how to go ahead.. 
     dataArray[0] = dataToSave;
     // Add more if required
     // dataArray[1] = {"result": '"' + toLength2.innerText +'"', "count": counter2};

     var savedData = JSON.stringify(dataArray);    
     writeToFile(filename, savedData);
}

Note: Please note that in a browser this is not going to work, as for security reasons browser is not going to allow javascript to acess the local file system depending upon the zone in which the site is running.
