+/* INFO: What are Truthy and Falsy Values?
 In JavaScript, every value is either "truthy" or "falsy" when evaluated in a Boolean context (like inside an if condition).
 
-- **Falsy values** are those that are considered false when converted to a Boolean.
-- **Truthy values** are all other values that are considered true.
