assertBoolean method

SassBoolean assertBoolean([
  1. String? name
])
override

Throws a SassScriptException if this isn't a boolean.

Note that generally, functions should use isTruthy rather than requiring a literal boolean.

If this came from a function argument, name is the argument name (without the $). It's used for error reporting.

Implementation

SassBoolean assertBoolean([String? name]) => this;
