How To Check For The Existence Of An Element In A Liquid Array (Shopify) Without Using Join

- 1 answer

I want to check for array values in an array created from a "split". Is there a way to do it without doing the following:

{%- assign blog_tags_string = blogs.news.all_tags | join ' ' -%}

{%- if blog_tags_string contains blog_title -%}
    {%- assign is_tag_page = true -%}
{%- else -%}
    {%- assign is_tag_page = false -%}
{%- endif -%}

{%- if blogs.news.all_tags contains blog_title -%}
