Description

+

Addition

Add two variables together to get the result.

Example: 3 + 4 The result will be 7.

-

Subtraction

Subtract one variable from another to get the result.

Example: 7 - 3 The result will be 4.

*

Multiplication

Multiply one variable to another to get the result.

Example: 3 * 4 The result will be 12.

/

Division

Divide one variable from another to get the result.

Example: 7/7 The result will be 1.

%

Modulus

This will grab the remainder from the division of two variables.

Example: 4/3 The result will be 1.

&&

Logical AND

If the two variables being compared are true, it will return true. If one or both are false, it will return false.

Example: If A = true, and B = false

A && B will result in false.

||

Logical OR

If one of the two variables being compared are true, it will return true. If both are false, it will return false.

Example: If A = true, and B = false

A || B will result in true.

!

Logical NOT

Returns the logical inverse of the variable.

Example: If A = true

!A will result in false.

<

Less Than

Will return true if the first variable is less than the second one, and will return false if not.

Example: A = 3, B = 4

A < B will result in true.

>

Greater Than

Will return true if the first variable is greater than the second one, and will return false if not.

Example: A = 3, B = 4

A > B will result in false.

<=

Less than or Equal to

Will return true if the first variable is less than OR equal to the second one, and will return false if not.

Example: A = 4, B = 4

A <= B will result in true.

>=

Greater than or Equal to

Will return true if the first variable is less than OR equal to the second one, and will return false if not.

Example: A = 5, B = 7

A >= B will result in false.

==

Equal to

Will return true if both variables are equal to each other, and will return false if not.

Example: A = 5, B = 5

A == B will result in true.

===

Instance of

Will return true if both variables are equal to each other and are the same type, and will return false if not.

Example: A = 1, B = '1'

A === B will result in false.

!=

Not equal to

Will return true if both variables are not equal to each other, and will return false if not.

Example: A = 2, B = 3

A != B will result in true.

in

In

Will check if the specific property exists within an object.

Example: myObj = {a: 1, b: 2, c: 3};

if ('a' in myObj) {
notification.send('Property "a" exists in myObj.'); // This will be executed
} else {
notification.send('Property "a" does not exist in myObj.');
}

This will result in “Property “a” exists in myObj being executed.
