Method return object instead of array

Question

I have one question. Why this method return object? In other part of my code i cant use forEach method.

objectToArrayOfObjects: function (obj, additionalProperties) {
    var arrayOfObjects = [];
    for (var name in obj) {
        if (obj.hasOwnProperty(name)) {
            var generatedObject = {name: name, value: obj[name]};
            arrayOfObjects.push(_.extend(generatedObject, additionalProperties));
        }
    }
    console.log(typeof arrayOfObjects); // return object
    return arrayOfObjects;
},

typeof [] === 'object'; because Arrays are essentially Objects in JavaScript. — Oleg

Everything inherits from Object in Javascript, so typeof returns object. The method does return an array, you can verify that by using: console.log(arrayOfObjects instanceof Array)

Or better - consider the array comming from another frame the above example would be false but looking at the constructors name instead would be ok: Object.prototype.toString.call(arrayOfObjects) === '[object Array]'

Or for that matter arrayOfObjects.constructor === Array, or /array/i.test(arrayOfObjects.constructor)

you may use $.each method of jquery to loop through the object.

This doesn't answer the question. Also, no need to use jQuery for something that could be accomplished in two lines of code.
