array of objects union has duplicates

[vabburi82]

var old_users = [{name:'Adam'},{name:'Aron'},{name:'Bob'}];
var new_users = [{name:'Alan'},{name:'Aron'},{name:'Ben'}];

var total_users = array.union(old_users, new_users);

console.log(total_users); // [{name:'Adam'},{name:'Aron'},{name:'Bob'},{name:'Alan'},{name:'Aron'},{name:'Ben'}]

This functions as intended. The comparison of duplicate values is a strict comparison. The two similar objects have the same value inside, but are not the same object.

As an example, internally it uses the unique method which by default compares with ===. Essentially the two objects {name:'Aron'} are not the same. If you type {name:'Aron'} === {name:'Aron'} into a console you will get false in return.

However, the union method should accept a comparison parameter which is a function that compares two arguments. The same way the union function does.
