Define a new array which will store the non-duplicate values. Then loop through the array which contains the values.

In each iteration, check if the non-duplicate array contains the value. If it does, ignore it. If it doesn't add it to the array.

I think someone did something similar recently. If I find it, I'll link to it (I can't be bothered rewriting it).

See this post. You'll have to adapt it - it was for a specific question.

The most general way is to assign a method for removing duplicates to all Arrays-
but first define indexAt.

Array.prototype.indexAt= function(wot){
    var L= this.length;
    var i= 0;
    while(i< L){
        if(this[i]=== wot)return i;
        ++i;
    }
    return -1;
}

And then the method that removes duplicates:

Array.prototype.unique= function(){
    var A= [],L,tem;
    L= this.length;
    for(var i= 0;  i< L;  i++){
        tem= this[i];
        if(A.indexAt(tem)!=-1)continue;
        A.push(tem);
    }
    return A;
}

var A2=someArray.unique(); or someArray=someArray.unique()
