How can I ensure newly created object styles are unique?

Question

Object styles seem to allow duplicate names as long as they're in different groups.
The condition

"if(!d.objectStyles.itemByName(a1).isValid)"

doesn't appear to check for "a1" within its own group.

Instead, it requires this approach:

if(!d.objectStyleGroups.itemByName(“AA”).objectStyles.itemByName(a1).isValid))

Since I don't know all group names, is there a way to check if the style `a1` exists in any group or outside all groups?

How to efficiently determine if there is an a1?

With an Array you have to loop, something like this

alert(checForOS("a1"))
  
/**
* Check if an object style named n exists 
* @ param n 
* @ return true if object style named n exists * 
*/
function checForOS(n){
    var os = app.documents.item(0).allObjectStyles;
    var b = false
    for (var i = 0; i < os.length; i++){
        if (os[i].name == n) {
            b = true
        } 
    }; 
    return b
}

You could use allObjectStyles to get an array, then check the array. P.
