Question

I have a very simple JavaScript array that may or may not contain duplicates.

var names = ["Mike","Matt","Nancy","Adam","Jenny","Nancy","Carl"];

I need to remove the duplicates and put the unique values in a new array.

I could point to all the code that I’ve tried but I think it’s useless because they don’t work. I accept jQuery solutions too.

Quick and dirty using jQuery:

var names = ["Mike","Matt","Nancy","Adam","Jenny","Nancy","Carl"];
var uniqueNames = [];
$.each(names, function(i, el){
    if($.inArray(el, uniqueNames) === -1) uniqueNames.push(el);
});
