Deprecated tags
Deprecated tags are Liquid tags that are considering as outdated, and we should no longer use them in our developing process. However, we may still encounter them inside some of the older themes, so it is important to recognize them and know what they do.
The only tag that Shopify has deprecated is the include tag, which works similarly to the render tag, which we have previously covered:
{% include "snippet-name" %}
The only key difference between the two is that when rendering a snippet using the include tag, the code inside our snippet can automatically access and modify the variables within its parent template. This not only creates a lot of performance issues but also makes our code a lot harder to maintain, which is why Shopify replaced it with the render tag.
