Incrementing variables in liquid without outputting them

Question

I am doing a for loop in shopify, I need to increment a variable.

However, when I do

{% increment variable %}

besides incrementing it, it shows the output on the screen!

I can't believe it. Is there a way to avoid this?

Thank you

If you are using a different logic for incrementing the value than forloop.index, you can use the plus filter to increment the variable:

{% assign variable = 0 %}
{% for … %}
  {% assign variable = variable | plus: 1 %}
{% endfor %}

I can also recommend that you have a look at the cheat sheet for Shopify.
