Booleans

bool_and(bool value1, bool value2): bool¶

Returns value1 && value2

bool_not(bool value) : bool¶

Returns !value

is_empty(any value): bool¶

Returns true if:

• value is "" (empty string)
• value is [] (empty array)
• value is null

is_null(any value) : bool¶

Returns true if value is null. An alternative to if (value == null) that won't break when value isn't null due to type checking.

Example:

value = 'example'
if (is_null(value)) {
  // Won't trigger a type error
}

to_bool(string/number/array/bool value) : bool¶

Casts value to a bool.
