list是處理一組有序專案的資料結構，即你可以在一個列表中儲存一個 序列 的專案。可以從列表的任何位置取出元素、插入元素。在JavaScript中這樣實現：

 <script>
        function List() {
            this.listSize = 0;
            this.pos = 0;
            this.dataStore = []; // 初始化一個空陣列來儲存列表元素
            this.clear = clear;
            this.find = find;
            this.toString = toString;
            this.insert = insert;
            this.append = append;
            this.remove = remove;
            this.front = front;
            this.end = end;
            this.prev = prev;
            this.next = next;
            this.length = length;
            this.currPos = currPos;
            this.moveTo = moveTo;
            this.getElement = getElement;
            this.length = length;
            this.contains = contains;
        }
        function append(element) {
            this.dataStore[this.listSize++] = element;
        }
        function find(element) {
            for (var i = 0; i < this.dataStore.length; ++i) {
                if (this.dataStore[i] == element) {
                    return i;
                }
            }
            return -1;
        }
        function remove(element) {
            var foundAt = this.find(element);
            if (foundAt > -1) {
                this.dataStore.splice(foundAt,1);
                --this.listSize;
                return true;
            }
            return false;
        }
        function length() {
            return this.listSize;
        }
        function toString() {
            return this.dataStore;
        }
        function insert(element, after) {
            var insertPos = this.find(after);
            if (insertPos > -1) {
                this.dataStore.splice(insertPos+1, 0, element);
                ++this.listSize;
                return true;
            }
            return false;
        }
        function clear() {
            delete this.dataStore;
            this.dataStore = [];
            this.listSize = this.pos = 0;
        }
        function contains(element) {
            for (var i = 0; i < this.dataStore.length; ++i) {
                if (this.dataStore[i] == element) {
                    return true;
                }
            }
            return false;
        }
        function front() {
            this.pos = 0;
        }
        function end() {
            this.pos = this.listSize-1;
        }
        function prev() {
            if (this.pos >= 0) {
                --this.pos;
            }
        }
        function next() {
            if (this.pos < this.listSize) {
                ++this.pos;
            }
        }
        function currPos() {
            return this.pos;
        }
        function moveTo(position) {
            this.pos = position;
        }
        function getElement() {
            return this.dataStore[this.pos];
        }
        //例項
        var names = new List();
        names.append("Cynthia");
        names.append("Raymond");
        names.append("Barbara");

        for(names.front(); names.currPos() < names.length(); names.next()) {
            console.log(names.getElement());
        }
        for(names.end(); names.currPos() >= 0; names.prev()) {
            console.log(names.getElement());
        }
        </script>
