javascript: typeerror (intermediate value) is not a constructor

It's been long time since i have written a blog post as i am busy with the project deliverable. So, here i am with one more issue which i faced today while writing some basic javascript code.

The error is 

javascript: typeerror (intermediate value) is not a constructor

i came across this issue when i am returning some object from a function. Following is the similar javascript code that i have written

function buildContact() {

        return new { name: "John", mobile: "123-456-7890", country: "US" };

    } 

this is the javascript function which was showing the mentioned error. 

Cause:

I used new which can be only used with a Function as operand. In this case i am using object as a constructor which is actually not. 

Fix:

Here we have two options to fix this error. 

1. To return object directly as shown below

function buildContact() {

        return { name: "John", mobile: "123-456-7890", country: "US" };

    }      

2. Create a constructor and use the constructor to create new object as shown below

function Contact(name, mobile, country) {

        this.name = name;

        this.mobile = mobile;

        this.country = country;

    }

    function buildContact() {

        return new Contact("John", "123-456-7890", "US");

    }

in this case we are returning the new Contact() by using constructor. 

In this way you can fix the error javascript: typeerror (intermediate value) is not a constructor.

Please do comment if you know better way to fix this error. Thanks in advance.
