Boolean

Boolean is a data type with two possible values: true and false.

Booleans are commonly used to represent the result of a condition, comparison, predicate, or flag.

For example:

isReady := true
isEmpty := len(items) == 0

Booleans are used in:

• Conditional logic
• Loop conditions
• Feature flags
• Predicate functions

Some languages also have truthy and falsy values, where non-boolean values are treated like booleans in conditional expressions. This is different from a strict boolean type.

Q: How is a strict boolean different from truthy and falsy values? A: A strict boolean has only true and false, while truthy and falsy rules treat non-boolean values as booleans in conditions.
