elseif statement can be used in cases where you want to extend the if statement by specifying another condition if the preceding condition is falsy.

  "product": {
    "track_inventory": true,
    "price": 100,
    "compare_at_price": 140,
    "slug": "youcan"
  }
}

liquid
{% if product.track_inventory == false %}
  First condition is truthy
{% elseif product.price < product.compare_at_price %}
  First condition is falsy, and the second condition is truthy
{% elseif product.slug == 'youcan' %}
  If both the first and second conditions are both falsy, and the third one is truthy
{% endif %}

Output
