Object handles
Objects represent store resources, such as products, collections, articles, and blogs, and have handles for identifying an individual resource.
Liquid Operators
Liquid supports basic logical and comparison operators for use with conditional tags.
Liquid Types
Liquid output can be one of six data types.
Liquid truthy and falsy
All data types must return either true or false. Those which return true by default are called truthy. Those that return false by default are called falsy.
