## Overview

Build a Wikipedia search app that fetches results from the Wikipedia API, displays them, and keeps track of the last 5 search terms with timestamps.


## Requirements

- Implement a search form that fetches results from the Wikipedia OpenSearch API:  
  `https://en.wikipedia.org/w/api.php?action=opensearch&search=SEARCH_TERM&format=json&origin=*`
- Display the search results as clickable links that open in a new tab.
- Track the last 5 search terms with timestamps.
  - Do not duplicate terms; if a term is searched again, move it to the most recent position.
  - Only keep the most recent 5 terms.
- Clear the search input after submitting a search.


## Notes

- Focus on handling the form submission properly.
- Use `toLocaleString()` to format timestamps in a readable way.
- Think about how to manage and update the search history efficiently.
- Ensure links open safely in a new tab (`target="_blank"` and `rel="noopener noreferrer"`).


## Tests

01. fetches and displays results
02. clears the input after submitting a search
03. keeps only the last 5 search terms without duplicates
04. does not duplicate a search term but moves it to the end
