Javascript Basic Relational Assignment Math Operators

Relational Operators
Operator	Function
v1==v2	Test that v1 and v2 are equal.
v1<>v2	Test that v1 and v2 are not equal.
v1>v2	Test that v1 is greater than v2.
v1>=v2	Test that v1 is greater than or equal to v2.
v1<v2	Test that v1 is less than v2.
v1<=v2	Test that v1 is less than or equal to v2.
v1&&v2	Evaluates the logical AND of v1 and v2.
v1\|\|v2	Evaluates the logical OR of v1 and v2.
!value	Evaluates the logical NOT of value.

Assignment Operators
Operator	Function
=	Assigns value to variable.
+=	Adds value to value already in variable.
-=	Subtracts value to value already in variable.
*=	Multiplities value with value already in variable.
/=	Divides value with value already in variable.
%=	Divides value with value already in variable; return remainder.

Math Operators
Operator	Function
- value	Treats the value as a negative number.
v1+v2	Add value v1 and v2 together, ads strings together.
v1-v2	Subtracts value v2 from v1.
v1*v2	Multiplies value v1 and v2.
v1/v2	Divides v1 by v2.
v1%v2	Divides v1 by v2; returns floating-point remainder
v1++	Adds 1 to v1.
v1--	Subtracts 1 from v1.
