# Javascript operators examples

Learn how to use operators in javscript, Assignment operator, Comparison operator, Logical operator, Bitwise operator, Arithmetic operator in Javascript.

## JavaScript Assignment Operators

 Operator Description Example = assigning the right side value to variable in left side a = b, means assigning the value of b to a += current value + new value var a = 10; a += 5; that means a will become a+5= 15 -= current value - new value var a = 10; a -= 5; that means a will become a-5= 5 *= current value * new value var a = 10; a *= 5; that means a will become a*5= 50 /= current value / new value var a = 10; a /= 5; that means a will become a/5= 2

JavaScript Comparison Operators

 Operator Description Example == equal to, check if both equal, Returns true or false a==b, means a equal to b != Not equal to, check if both not equal, Returns true or false a!=b, means a not equal to b > greater than, Returns true or false a>b, means a greater than b >= greater than equal to, Returns true or false a>=b, means a greater than equal to b < less than, Returns true or false a

JavaScript Logical Operators

 Operator Description Example || OR (a === 10 || b === 5) is false && AND (a < 10 && b >5) is true ! NOT !(a == b) is true
JavaScript Bitwise Operators
 Operator Description Example ~ NOT a = ~ 5 ^ XOR a = 5 ^ 1
JavaScript Arithmetic Operators

Here we use two variable (a=10, b=5) to show you the examples below.

 Operator Description Example % Modulus (division remainder) a % b : ++ Increment a = b++ : -- Decrement + Addition - Subtraction * Multiplication / Division
