Logical Operators

Operator	Description	Example
&&	and	(x < 10 && y > 1) is true
\|\|	or	(x==5 \|\| y==5) is false
!	not	!(x==y) is true

Comparison Operators

Comparison operators are used in logical statements to determine equality or difference between variables or values. In this table, the x-variable has a value of 5 to explain the JavaScript Comparison operators: Operator Description Comparing Returns == is equal to x==8 false x==5 true != is not equal to x!=8 true > is greater than x>8 false < is less than x<8 true >= is greater than or equal to x>=8 false <= is less than or equal to x<=8 true Parent topic: Operators

Arithmetic Operators

These operators are used to perform arithmetic between variables and/or values. In this table, the y-variable has a value of 5 to explain the JavaScript Arithmetic operators: Operator Description Example Result of x Result of y + Addition x=y+2 (5+2) 7 5 - Subtraction x=y-2 (5-2) 3 5 * Multiplication x=y*2 (5*2) 10 5 / Division x=y/2 (5/2) 2.5 5 % Modulus (division remainder) x=y%2 (remainder is 1 for the equation 5/2) 1 5 ++ Increment x=++y (++6) 6 (a) 6 (b) x=y++ (6++) 5 (c) 6 (b) -- Decrement x=--y (--4) 4 (d) 4 (e) x=y-- (4--) 5 (f) 4 (e) (a) The increment occurs before the variable, so x is the incremented value of y, which is 6; (b) The value is 6 because y, which is 5, is increased by 1 for this operator; (c) The increment occurs after the variable, so x is the original value of y, which is 5; (d) The decrement occurs before the variable, so x is the decremented value of y, which is 4; (e) The value is 4 because y, which is 5, is decreased by 1 for this operator; (f) The decreme

Assignment Operators

These operators are used to assign values to JavaScript variables. In this table, the x-variable has a value of 10, and the y-variable has a value of 5 to explain the JavaScript Assignment operators: Operator Description Example Same As Result = assign x=y x=y (5) x=5 += add and assign x+=y x=x+y (10+5) x=15 -= subtract and assign x-=y x=x-y (10-5) x=5 *= multiply and assign x*=y x=x*y (10*5) x=50 /= divide and assign x/=y x=x/y (10/5) x=2 %= modulus (division remainder) and assign x%=y x=x%y (remainder is 0 for the equation 10/2) x=0 Parent topic: Operators
