Logical Operators

Supported logical operators to manipulate and combine Boolean values and to construct conditional statements.

Operator	Name	Description	Applicable Data Types	Return Data Type	Example
\|\|	OR	Returns the result of combining Boolean values using a logical OR. If one value or expression contained in the OR statement evaluates to true, the OR expression returns true.	Boolean	Boolean	`true \|\| false;` `//returns true`
&&	AND	Returns the result of combining Boolean values using a logical AND. If both values or expressions in the AND statement evaluate to true, the AND expression returns true.	Boolean	Boolean	`true && false;` `//returns false`
!	NOT or Inversion	Negates the specified Boolean value. Applying the NOT operator to an expression that evaluates to true will return false.	Boolean	Boolean	`!true;` `//returns false`
