How to convert forEach in a for loop using key and value?

Question

Trying to send form data in JSON format but IE does not support formData.forEach

 var form = document.querySelector('#Form');
             var formData = new FormData(form);
             var object = {};
             formData.forEach(function(value, key){
                 object[key] = value;
             });
             var json = JSON.stringify(object);
             xhr.send(json);

How can I convert that forEach in for loop? Also, I've already added the polyfill so it's not that

If you don't mind using libraries, UnderscoreJS has a lot of pretty useful functions (including `forEach` and many others). https://underscorejs.org/ — Dortimer, Dec 11 '19 at 20:48

`FormData` does not have a `forEach` method. You can turn it into an array using `formData.getAll()`, at which point the polyfill should allow you to use `.forEach()` on the resulting array. — Tyler Roper, Dec 11 '19 at 20:49

After reading the comments and links that people provided me, this worked for me.

var object = {};
 var dataArray=($("#form").serializeArray());
    for (var i in dataArray) {
         object[dataArray[i].name] = dataArray[i].value;
    }
 var json = JSON.stringify(object);
