Javascript “Not a Constructor” Exception while creating objects

Question

I am defining an object like this:

function Project(Attributes, ProjectWidth, ProjectHeight)
{
    this.ProjectHeight = ProjectHeight;
    this.ProjectWidth          


        

Answer 1

In my case I was using the prototype name as the object name. For e.g.

function proto1()
{}

var proto1 = new proto1();

It was a silly mistake but might be of help to someone like me ;)
