Learning the comparison operators

With Liquid, we have access to seven comparison operators, which we can combine to create any type of logical flow that our code requires. Let's review them as follows:

  • The == operator allows us to check whether the element we are comparing is equal to some value:
    {% if collection.title == "Winter Shoes" %}
      Winter Shows collection found!
    {% endif %}

    If collection.title is strictly equal to our string of "Winter Shows", the logic returns true, and we will see our message shown. Otherwise, the logic returns false. Note that comparison will only return true if the string is an exact match, including the text case.

    {% if collection.title != "Winter Shows" %}
      Winter Shows collection is not found!
    {% endif %}
