+title: Truthy and Falsy
+---
+
+In programming, anything that returns `true` in a conditional is called **truthy**. Anything that returns `false` in a conditional is called **falsy**. All object types can be described as either truthy or falsy.
+
+## Truthy
+
+All values in Liquid are truthy except `nil` and `false`.
+
+In the example below, the text "Tobi" is not a boolean, but it is truthy in a conditional:
+
+{% highlight liquid %}{% raw %}
+{% assign tobi = 'Tobi' %}
+
+{% if tobi == true %}
+  This condition will always be true.
+{% endif %}
+{% endraw %}{% endhighlight %}
+
+[Strings](/basics/types/#string), even when empty, are truthy. The example below will result in empty HTML tags if `settings.fp_heading` is empty:
+
+<p class="input">Input</p>
+{% highlight liquid %}{% raw %}
+{% if settings.fp_heading %}
+  <h1>{{ settings.fp_heading }}</h1>
+{% endif %}
+{% endraw %}{% endhighlight %}
+
+<p class="output">Output</p>
+{% highlight html %}{% raw %}
+<h1></h1>
+{% endraw %}{% endhighlight %}
+
+[EmptyDrops](/basics/types/#emptydrop) are also truthy. In the example below, if `settings.page` is an empty string or set to a hidden or deleted object, you will end up with an EmptyDrop. The result is an empty `<div>`:
+
+<p class="input">Input</p>
+{% highlight html %}{% raw %}
+{% if pages[settings.page] %}
+  <div>{{ pages[settings.page].content }}</div>
+{% endif %}
+{% endraw %}{% endhighlight %}
+
+<p class="output">Output</p>
+{% highlight html %}{% raw %}
+<div></div>
+{% endraw %}{% endhighlight %}
+
+## Falsy
+
+The falsy values in Liquid are [nil](/basics/types/#nil) and [false](/basics/types/#boolean).
+
+## Summary
+
+The table below summarizes what is truthy or falsy in Liquid.
