Relational Operators

Operator	Purpose
==	Equal
!=	Not equal
<	Less than
<=	Less than or equal
>	Greater than
>=	Greater than or equal

These are used to compare two values. Note that equality is checked via ==, not =.

As we learned, = is an assignment operator, which assigns a value to a variable. It does not check if the value of the variable is the same as another value.

Example

def a = 1 (variable a now holds value 1)

def b = 1 (variable b now holds value 1)

To check if variable a is equal to variable b:

a == b

Logical Operators

Operator	Purpose
&&	AND
||	OR
!	NOT

These are the most important logical operators in the context of Sales Cloud. For a complete list of all the Logical Operators, please check this link.

However, it is doubtful you will use any other logical operators while scripting in Application Composer.

&& (AND)

When we use this operator, we want all the conditions to be met at the same time before an action is done.

For example:

def a = 1

def b = 2

def c = 1

a == c && a < b (both conditions have to be met at the same time before code continues to execute)

|| (OR)

When we use this operator, we want at least one of the conditions to be met before we continue.

For example:

def a = 1

def b = 2

def c = 1

a == c || a == b (if one of the two conditions is true, the code continues to execute. In this case, a == c is true, so our code will continue execution)

! (NOT)

This operator gives the reverse of a Boolean value.

So if we say !true, that means false. If we do !false, that means true.
