I have an orientational question that i'm not quite sure how to approach, so this is a request for advice.

For a project i'm working on i would like to assemble 'custom' variable names. For example, lets say i have this html page:

```
<div id="content">
    <div id="variable"></div>
    <div id="name"></div>
    <div id="custom"></div>
</div>

```

Now i know i can get the id's in jQuery with `$('div').attr('id')`. This is where my problem comes in:

I would like to create something like this line:

```
var variable_name_custom = 'Hello world';

```

where the var-name is generated by getting the div id's. (string div 1 + string div 2 + string div 3). 

If i were to put the 3 names together right now, i would get the string 'variable\_name\_custom', but it would be a string-value of a variable, rather than the name of one.

Is this possible?
