JavaScript Basics Tutorial Arithmetic operators

Operator	Operator description	Example	Example description
+	Addition	X+y	If x is an integer 2,y is an integer 5, x+y equals 7 If x is the string "Text1" and Y is the string "fun", X+y is equal to "Text1fun"
-	Subtraction	X-y
*	Multiplication	X*y
/	Division	x/y
%	Divide the two to find the remainder	X%y	If x equals ten, Y equals 3, the x%y result equals 1.
++	Increasing	X + +	x + + equals 11 if × is equal to
--	Decline	y--	If y equals ten, y--equals 9.

JavaScript Basics Tutorial Logical operators

Operator	Operator description	Example	Example description
==	Equals	X==y	If x equals 2, and y equals 2, then x==y
===	All Equals (equal value, same data type)	X===y	If x equals integer 2,y to the string "2", Then x===y not set up
>	Greater than	X>y
>=	Greater than or equal to	X>=y
<	Less than	X<y
<=	Less than or equal to	X<=y
!=	Not equal to	X!=y
!==	Not all equal to	X!==y
&&	With (and)	X < ten && y > 1
!	Non (not)	! (x==y)
||	or (OR)	x==8 | | Y==8

JavaScript Basics Tutorial Assignment operators

Operator	Operator description	Example	Example description
=	assigning values	X=5	Assign the value of integer 5 to the variable x
