The full URL of an article is `https://en.wikipedia.org/wiki/ARTICLE`; for example, the URL for the Unicode article is https://en.wikipedia.org/wiki/Unicode.
You can use Node.js's [`https.get()`](https://nodejs.org/api/https.html#https_https_get_options_callback) function to make the requests.
There are a few types of links that need special handling:
- Links to special Wikipedia pages, e.g. `href="/wiki/Template:Latin_alphabet_sidebar"`.
You can identify these links by the `:`.
They aren't real pages, so you should skip them.
- Links to sections on the same page, e.g. `href="#History"`.
You can identify these links by the `#` at the start of the link.
Again, since the link points to the same page, you don't need to follow it.
- Links to sections on other pages, e.g. `href="/wiki/Article_(grammar)#Indefinite_article"`.
You can identify these links by the `#` in the middle of the link.
To follow this link, remove the part starting with `#`.
In this example, that would be `/wiki/Article_(grammar)`.
## Implementing the Wikipedia search
The general idea is to start at the source article, follow each link to another Wikipedia article, and stop upon reaching the target article.
