adding property to array element in javascript

Question

I'm trying to learn and understand javascript.

what is wrong with the following code?

var d=[];
d[0]=document.createElement('div');
d[0].title=document.createElement('div');
d[0].appendChild(d[0].title);

I get this error: TypeError: Argument 1 of Node.appendChild is not an object.

Can you suggest a solution?

This line d[0].appendChild(d[0].title); is expecting an element to be appended to the div. Your simply appending a text node. Create another div (or whatever element you want) and append that.

Is there a way to create that div as a property of d[0]?

@user2799563 -- d[0] is a position in an array, that currently holds a div, use d[1]

The problem is that the name title is reserved. Try a different name.

.title is an attribute of the element, which is a string. When you try to append something to that attribute it is expecting a string.
