Simple way to set views count of product in Craft Commerce

While developing Craft Commerce based website, we would apply different fileters and sorting on product listing page. Also, apply sorting based product popularity or products views. Here, I would like to mention simplest way to set product's view count in just few steps:

1.  Create a Number type field like “Total Views” and assign this field to product type.
2.  Within the product template, write this code to increment to view count whenever a product page is opened:
   {# set product view count #}
{% set currentTotalViewCount = product.totalViews|default(0)  %}
{% do product.setFieldValue('totalViews', currentTotalViewCount + 1) %}
{% do craft.app.getElements().saveElement(product) %}
3. Now just apply order by on product listing page like:
   {% set productQuery = craft.products().type('productType').orderBy('totalViews DESC') %}
   
   That's it …
