+Though [shopify-liquid][sl] is designed platform-independent, there're certain differences with [the Ruby version][ruby], one of which is the `truthy` evaluation.
+
+Everything other than `false` and `nil` is truthy in the ruby version, see: <https://shopify.github.io/liquid/basics/truthy-and-falsy/>
+
+In this JavaScript version, things are slightly different:
+
+value        | truthy | falsy
+---          | ---    | ---
+`true`         | ✔️ | 
+`false`        |    | ✔️
+`null`         |    | ✔️
+`undefined`    |    | ✔️
+`string`       | ✔️ |	 
+`empty string` | ✔️ |
+`0`            | ✔️ |
+`integer`	     | ✔️ | 
+`float`	     | ✔️ |
+`array`        | ✔️ | 
+`empty array`  | ✔️ |
