I read the official docs of Liquid but couldn’t find the info that I was looking for.

In the end, the below code worked for me:

{% if string != nil and string != '' %}
    Do whatever with string
{% endif %}

Example code:

{% assign name="Blog" %}
{% if name != nil and name != '' %}
    Yay!
{% else %}
    Nay
{% endif %}

Output:

Yay!
