Boolean Literals

Booleans represent truth values and can be either true or false. They are essential for controlling program flow with conditional statements.

{{ isAdmin = true }}

@if(isAdmin)
    <button>Delete User</button>
@else
    <p>You don't have permission</p>
@end

Truthy values

Non-empty strings, non-zero numbers (including negatives), non-empty arrays, and objects with at least one key are truthy.

Falsy values

false, nil, 0, 0.0, empty strings "", empty arrays [], and empty objects {} are falsy.

Printed as 1 and 0

Outputting a boolean renders 1 for true and 0 for false. Use a ternary expression if you need "true" or "false" text.
