How to include an array of data in an $http request using AngularJS

I am trying to store data in an array to the $http service in AngularJS. The way I am currently adding them to the service is as follows (and it is functioning correctly):

var inputValueArray  = new Array($scope.formdata);

Currently, I am able to retrieve data using index zero in my API. However, I want to be able to retrieve data using a named index. So, I tried the following:

var inputValueArray  = new Array();
inputValueArray["myIndex"] = $scope.formData;

Unfortunately, when I try to retrieve data in the API, I get an empty array. I then attempted the following solution:

var inputValueArray = {"myIndex" : $scope.formData};

Now, I am encountering a Maximum call stack size exceeded error. In both cases, I am using $_POST to receive the data. I am sending the data using $.param() like this:

data: $.param({ mydata:inputValueArray , csrf_token: myTokenKey})

Any suggestions or ideas would be greatly appreciated.

In the ECMAScript 2015 (ES6) standard, javascript includes a Map implementation.

Visit this link

For example:

var myMap = new Map();

var keyString = "a string",
    keyObj = {},
    keyFunc = function () {};

// Assigning values
myMap.set(keyString, "value associated with 'a string'");
myMap.set(keyObj, "value associated with keyObj");
myMap.set(keyFunc, "value associated with keyFunc");

myMap.size; // 3

// Retrieving the values
myMap.get(keyString);    // "value associated with 'a string'"
myMap.get(keyObj);       // "value associated with keyObj"
myMap.get(keyFunc);      // "value associated with keyFunc"

myMap.get("a string");   // "value associated with 'a string'"
                         // because keyString === 'a string'
myMap.get({});           // undefined, because keyObj !== {}
myMap.get(function() {}) // undefined, because keyFunc !== function () {}
