Syntax

value.not() → result

​
Arguments

No arguments.

​
Optargs

No optional arguments.

​
Returns

​
result
boolean
Returns true if the value is false, and false if the value is true.

​
Behavior

  • Inverts the boolean value of the expression.
  • Converts truthy values to false and falsy values to true.
  • Commonly used to negate conditions in filters and logical expressions.
  • Can be chained with other logical operators for complex conditions.

​
Notes & Caveats

  • The not() function operates on boolean values or expressions that evaluate to boolean.
  • When used with non-boolean values, RuloDB’s truthiness rules apply.
  • Can be combined with other logical operators like and and or.
