Every developer has more ideas than time. As David Allen likes to say “the human brain is for creating ideas, not remembering them.” In this project, we’ll be building a simple application for recording and archiving our ideas (good and bad alike).

Throughout the project, one of our focuses will be on providing a fluid and responsive client-side interface. To this end, we’ll rely on JavaScript and jQuery to implement snappy filtering in the browser, and localStorage to persist our wonderful ideas between sessions.

Project Requirements


For this project, we’ll be increasingly thinking about the “server” and “client” as separate entities. We’ll be using:

  • JavaScript (with jQuery) to manage client-side interactions.
  • JSON and localStorage to persist data between sessions.

Your entire application will consist of one HTML page or template.

Data Model

  • An Idea has an id, title, a body, and a quality.
    • The id should be a unique identifier.
    • title and body are free-form strings.
  • quality should be one of the follow: “genius”, “plausible”, and “swill.”
  • By default, the idea’s “quality” should default to the lowest setting (i.e. “swill”).

User Flows

Viewing ideas

When visiting the application, the user should:

  • See a list of all existing ideas, including the title, body, and quality for each idea.
  • Ideas should appear in descending chronological order (with the most recently created idea at the top).

Adding a new idea

On the application’s main page, a user should:

  • See two text boxes for entering the “Title” and “Body” for a new idea, and a “Save” button for committing that idea.

When a user clicks “Save”:

  • A new idea with the provided title and body should appear in the idea list.
  • The text fields should be cleared and ready to accept a new idea.
  • The page should not reload.
  • The idea should be persisted. It should still be present upon reloading the page.

Deleting an existing idea

When viewing the idea list:

  • Each idea in the list should have a link or button to “Delete” (or 𝗫).
  • Upon clicking “Delete”, the appropriate idea should be removed from the list.
  • The page should not reload when an idea is deleted.
  • The idea should be removed from localStorage. It should not re-appear on next page load.

Changing the quality of an idea

As we said above, ideas should start out as “swill.” In order to change the recorded quality of an idea, the user will interact with it from the idea list.

  • Each idea in the list should include an “upvote” and “downvote” button.
  • Clicking upvote on the idea should increase its quality one notch (“swill” → “plausible”, “plausible” → “genius”).
  • Clicking downvote on the idea should decrease its quality one notch (“genius” → “plausible”, “plausible” → “swill”).
  • Incrementing a “genius” idea or decrementing a “swill” idea should have no effect.

Editing an existing idea

  • When a user clicks the title or body of an idea in the list, that text should become an editable text field, pre-populated with the existing idea title or body.
  • The user should be able to “commit” their changes by pressing “Enter/Return” or by clicking outside of the text field.
  • If the user reloads the page, their edits will be reflected.

Idea Filtering and Searching

We’d like our users to be able to easily find specific ideas they already created, so let’s provide them with a filtering interface on the idea list.

  • At the top of the idea list, include a text field labeled “Search”.
  • As a user types in the search box, the list of ideas should filter in real time to only display ideas whose title or body include the user’s text. The page should not reload.
  • Clearing the search box should restore all the ideas to the list.

You will need the svg files for the delete, upvote, and downvote icons. Here’s the link.


Go for it!! :muscle:


Add an optional third text field upon idea creation for “Tags”. Tags should be a comma-separated list of short text tags, and should be processed on the server such that any existing tags are re-used, and any new ones are created. Once there are tags to display, a list of existing tags should appear at the top of the idea list. Clicking one of these tags should show only ideas that include it. When viewing ideas filtered by tag, be sure to include a link to take the user back to “All Ideas”. This filtering could be implemented either as a separate page or via javascript within the same interface.


When viewing the ideas list, the user should have the option to sort ideas by Quality. The default sort should be descending (“genius” → “plausible” → “swill”), and clicking the sort a second time should reverse it. The Idea list should be sorted client-side without reloading the page.

Student Directed Extension

Student chooses an additional feature or performance optimization to add to the project. The extension must be intuitive and should not detract from the user’s experience in any major way (i.e. not buggy or incomplete).

Exceptional Comfortable with using callback functions where applicable. Comfortable returning collections from functions (objects, arrays).


Novice Can create array and use array indexing to extract data from array or modify array. Comfortable using arrays to store simple data types: numbers, booleans, or strings.
Advanced Beginner Can modify arrays by adding or removing specific elements - uses array methods such as push or shift. Can use a for loop to iterate through array.
Proficient Does not use for loops for arrays - uses array prototypes, such as forEach, to iterate through or manipulate arrays. Can use array to store more complicated data structures such as objects or nested arrays. Is comfortable/efficient with reading array prototype documentation and can efficiently test/apply array prototype methods they have not worked with before.
Exceptional Uses variety array prototypes to iterate through arrays and manipulate/create new arrays without using documentation as a resource.

Advanced Beginner Can accomplish about 50-75% of the large and small design details and can logically rework them on at least 1 breakpoint.
Proficient Developer captures the spirit and design intent of the comp. Some small details need polish to achieve a pixel-perfect match to the comp, but developer is clearly mindful of details and has made a conscious and careful effort to match the comp. Any design decisions left open to interpretation are handled thoughtfully and are well executed, but are more noticeable and/or unintuitive than they would be if the designer had provided the solution, or may not be totally seamless during screen-size transitions.
Exceptional Developer skillfully captures the spirit and design intent of all comp details. Execution is pixel-perfect and any design decisions left open to interpretation are solved intentionally, are as seamless as if the designer had provided the solution, are handled gracefully, and enhance the overall design.



Novice Can communicate needs, expectations, scheduling constraints through a DTR, effectively creating a working plan with partner.
Advanced Beginner Can identify deltas in skill level and collaborate on methods whereby both pairs can share equitably in the workload. Can revisit the DTR to address changes that arise, and/or simply to keep one another reminded of the working plan.
Proficient Can diplomatically handle issues that arise between the pair through respectful, focused, targeted feedback and implement changes to positively adapt the working relationship and keep the project on track. Can effectively implement tactics to support their partner’s learning and project goals, while also honoring their own personal learning and project goals, should the two be different or at different levels due to skill delta.
Exceptional Pair collaboration and communication is exceptional, with the distribution of work being equal and balanced, and both partners experiencing a good working flow, able to handle stress, deadlines, issues with calm and focused demeanor.
