Just wondering what the most efficient way to check whether a section has any entries or not. Based on this, I'm showing some content. The content doesn't take any information from the entries in the section, so it'll be a superfluous query no matter what.
For context, this is basically what it'll look like:
{% if craft.entries.section('whatever') | length > 0 %}
<a href="www.com">Go here</a>
{% endif %}
