Add External Stylesheets/Pens

Any URL's added here will be added as <link>s in order, and before the CSS in the editor. If you link to another Pen, it will include the CSS from that Pen. If the preprocessor matches, it will attempt to combine them before processing.

You're using npm packages, so we've auto-selected Babel for you here, which we require to process imports and make it all work. If you need to use a different JavaScript preprocessor, remove the packages in the npm tab.

Add External Scripts/Pens

Any URL's added here will be added as <script>s in order, and run before the JavaScript in the editor. You can use the URL of any other Pen and it will include the JavaScript from that Pen.

Use npm Packages

We can make npm packages available for you to use in your JavaScript. We use webpack to prepare them and make them available to import. We'll also process your JavaScript with Babel.

⚠️ This feature can only be used by logged in users.

  We are going to approximate an implementation of ArrayList. In JavaScript terms, that means we are
  going to implement an array using objects. You should not use arrays at all in this exercise, just
  objects. Make a class (or constructor function; something you can call new on) called ArrayList.
  ArrayList should have the following properties (in addition to whatever properties you create):
  length - integer  - How many elements in the array
  push   - function - accepts a value and adds to the end of the list
  pop    - function - removes the last value in the list and returns it
  get    - function - accepts an index and returns the value at that position
  delete - function - accepts an index, removes value from list, collapses, 
                      and returns removed value

  As always, you can change describe to xdescribe to prevent the unit tests from running while
  you work

// unit tests
// do not modify the below code
describe('ArrayList', function() {
  const range = length => Array.apply(null, {length: length}).map(Number.call, Number);
  const abcRange = length => range(length).map( num => String.fromCharCode( 97 + num ) );
  let list;
  beforeEach( () => {
    list = new ArrayList();
  it('constructor', () => {
  it('push', () => {
    abcRange(26).map( character => list.push(character) );
  it('pop', () => {
    abcRange(13).map( character => list.push(character) );
    range(10).map( () => list.pop() );
  it('get', () => {
    abcRange(26).map( character => list.push(character));
  it('delete', () => {
    abcRange(26).map( character => list.push(character) );
🕑 One or more of the npm packages you are using needs to be built. You're the first person to ever need it! We're building it right now and your preview will start updating again when it's ready.
