How do I add a property to a JavaScript object using a variable as the name?

I'm trying to achieve the following, push an anonymous object into an array, but using the variable 'name' as the Object key. Any ideas how I could achieve this?

var json = $('form[name="edit-form"]').serializeArray();
var data = {};
data.user = [];
var l = json.length;
for(var i = 0; i < l; i++){
  var name = json[i].name;
  var value = json[i].value;
  data.user.push({[name]: value});
}

This question is not a duplicate of any of the examples you have cited. It additionally asks about pushing an anonymous object into an array. — Aamir, Mar 07 '17 at 15:49

Something like this? Assuming what you are looking for is an object with a property taken from the name variable containing the value.

    var json = $('form[name="edit-form"]').serializeArray();
    var data = {};
    data.user = [];
    var l = json.length;
    for(var i = 0; i < l; i++){
        var name = json[i].name;
        var value = json[i].value;
        var tempObj = {};
        tempObj[name] = value;
        data.user.push(tempObj);
    }
