Answer:
As we know Nunjucks is inspired by Jinja2 python’s template engine, the if statement is similar to it.
// And Snippet
{% if (VARIABLE > 10) and (VARIABLE < 20) %}
//
{% endif %}
// Or Snippet
{% if (VARIABLE == 10) or (VARIABLE == 20) %}
//
{% endif %}
Thats it !!!
Couldn’t find this on Nunjucks documentation either. I believe this answer will be helpful as coders working on Nunjucks tend to search with keyword Nunjucks and not with Jinja.
