Chrome Console and Javascript Object Type


The Prey you are seeing is the Prey when you do function Prey(){};, thus, the function name is Prey. If you define Prey as var Prey = function(){}; then the function name is "";

So basically if you want use the function name, you must give your constructor a name. var Prey = function Prey(){};

EDIT: or its possible that you did a variation of this:

var A = function NAMED(){};
var B = function(){};
B.prototype = Object.create(A.prototype);
var o = new B();

> o 
< B {};

> o.constructor.name
< "NAMED"

So, what is happening is the call to document.getElementById("error") is not retuning any results, and therefore the call to .innerHtml accomplishes nothing. What you need to do is defer the call to document.getEle

In designing a Javascript API, should I raise a TypeError or ignore with a console message?
I mainly do the following: In synchronous public APIs I always check parameters and throw the appropriate error. Not only TypeError but also other errors as appropriate.

I think console.log(...) and go on is not a good idea

How to close google chrome using javascript?
You could try using: self.close(); It works in Chrome, Safari, IE but not sure about Firefox. Also, there's a new way to close windows using the new method window.close() in the dev version of Chrome: see here. But I recommend using the first method as it currently works.
