Remove duplicate objects from a list

objects have arbitrary keys & values, uniqueness defined by combination of key & value

JavaScript

var data = [{'one':1},{'two':2},{'three':3},{'four':4},{'five':5},{'one':1}];
var tempMap = {};    // keep track of unique objects with key mapping to the object's key&value
var distinct = [];    // resulting list containing only unique objects
var obj = null;
for (var i = 0; i < data.length; i++) {
    obj = data[i];
    for (var key in obj) {        // look in the object eg. {'one':1}
        if (obj.hasOwnProperty(key)) {
            if (!tempMap.hasOwnProperty(key + obj[key])) {    // not in map
                tempMap[key + obj[key]] = obj;        // then add it to map
                distinct.push(obj);    // add it to our list of distinct objects
            }
            break;
        }
    }
}
console.log(distinct);
console.log(data);
