# --description--

**Objective:** Build a [CodePen.io](https://codepen.io) app that is functionally similar to this: <https://codepen.io/freeCodeCamp/full/wGqEga/>.

Fulfill the below [user stories](https://en.wikipedia.org/wiki/User_story). Use whichever libraries or APIs you need. Give it your own personal style.

**User Story:** I can search Wikipedia entries in a search box and see the resulting Wikipedia entries.

**User Story:** I can click a button to see a random Wikipedia entry.

Hint #1: Here's a URL you can use to get a random Wikipedia article: `https://en.wikipedia.org/wiki/Special:Random`.

Hint #2: Here's an entry on using Wikipedia's API: `https://www.mediawiki.org/wiki/API:Main_page`.

Hint #3: Use this [link](https://en.wikipedia.org/wiki/Special:ApiSandbox#action=query&titles=Main%20Page&prop=revisions&rvprop=content&format=jsonfm) to experiment with Wikipedia's API.

When you are finished, include a link to your project on CodePen and click the "I've completed this challenge" button.

You can get feedback on your project by sharing it on the [freeCodeCamp forum](https://forum.freecodecamp.org/c/project-feedback/409).
