Hard-coding urls makes changing URLs harder, and makes linking to the wrong page easier - so harms maintainability.

Django encourages giving URLs a name so they can be resoved later (rather than hard coding the URL).

This be taken advantage of by defining a `name` in the url.py entry, and then using that name in templates.

So in practice, do this

    # in urls.py
    urlpatterns = [
        path('articles/', Articles.as_view(), name='articles-list'),
    ]

    # in index.html
    <a href="{% url 'articles-list' %}">Go to articles</a>

Instead of this

    # in urls.py
    urlpatterns = [
        path('articles/', Articles.as_view()),
    ]

    # in index.html
    <a href="/articles/">Go to articles</a>
