{% if product.available %}In stock{% endif %} {# Logic tag #}
{% assign sale = product.price | times: 0.8 %} {# Assignment #}
{%- if condition -%}Stripped whitespace{%- endif -%}
Key patterns:
{% for product in collection.products limit: 5 %}
{% render 'product-card', product: product %}
{% endfor %}
{% paginate collection.products by 12 %}
{% for product in paginate.collection.products %}...{% endfor %}
{{ paginate | default_pagination }}
{% endpaginate %}
