Operators

  • JavaScript operators are symbols that are used to perform different operations on values and operands.

Example:

var add=10+10;  

Operators in JavaScript.

  1. Arithmetic Operators
  2. Comparison (Relational) Operators
  3. Bitwise Operators
  4. Logical Operators
  5. Assignment Operators
  6. Special Operators

Arithmetic operators:

Example:

var x = 10;
var y = 3;
var sum = x + y; // sum is 13
var product = x * y; // product is 30

Comparison operator:

Example:

var a = 5;
var b = "5";
a == b; // true, loose equality
a === b; // false, strict equality

Bitwise operator:

Example:

var a = 5; // Binary: 0101
var b = 3; // Binary: 0011
var result = a & b; // Bitwise AND: 0001 (Decimal 1)

Logical operator:

Example:

var isTrue = true;
var isFalse = false;
var result = isTrue && isFalse; // result is false

Assignment operator:

Example:

var a = 5;
a += 3; // equivalent to a = a + 3, a is now 8
