JavaScript operators are used to perform to the operations like arithmetic, assign the values, comparison values and check the condition s and more…

Per suppose “var c = a + b “; var is a key word and a, b, c are operands then =, + are operators.

We have number of operators like below

- Javascript Arithmetic Operators
- Javascript Relational Operators
- Javascript Logical Operators
- Javascript Arithmetic Assignment Operators
- Javascript Assignment Operators
- Javascript Conditional Operators
- Javascript Boolean Operators
- Javascript Increment & Decrement Operators
- Javascript Bitwise Operators or Javascript Ternary Operators

__Javascript Arithmetic Operators:-__

Arithmetic operators are used to perform all arithmetic operations like addition, subtractions, multiplication, division, modulus ….etc

These operators are [+,-,*,/,%].

JavaScript supports the following arithmetic operators – we are going to assign variable x, y. x have 10 and variable y have 20, then

S.NO | Operator & Description |

1 | + Addition
Adds two operands Ex: x + y will give 30 |

2 | – Subtraction Subtracts the second operand from the first Ex: x – y will give -10 |

3 | * Multiplication Multiply both operands
Ex: x * y will give 200 |

4 | / Division Divide the values and quotient will take
Ex: y/ x will give 2 |

5 | % Modulus Outputs the remainder will take here
Ex: y % x will give 0 |

__Javascript Relational Operators__:-

The relational operators are going to comparison any using this operators like <, >, <=, >=,! =

JavaScript following comparison operators – per example variable X have 10 and variable Y have 20, then

S.NO | Operator & Description |

1 | > Greater than
Compare two operands Ex: x > y will give “not true” |

2 | < Less than
Compare two operands Ex: x < y will give “true” |

3 | >= GreaterthanorEqualto
Compare two operands Ex: x >= y will give “ not true” |

4 | <=LessrthanorEqualto
Compare two operands Ex: x <= y will give “ true” |

5 | != NotEqualto
Compare two operands Ex: x != y will give “true” |

__Javascript Logical Operators__:-

The Logical operators are going to perform logical operations like **&&, || , !**

JavaScript following logical operations – per example variable X have 10 and variable Y have 20, then

S.NO | Operator & Description |

1 | && LogicalAND
If both the operands are non-zero, then the condition becomes true EX:- x&&y is “ true ” |

2 | || LogicalOR
If any of the two operands are non-zero, then the condition becomes true EX:- x||y is “ true ” |

3 | ! LogicalNOT
It reverse the logical state of it’s operands in this case the login is true then it will false the statement EX:- !x&&y is “ false ” |

__Javascript Arithmetic Assignment Operators__:-

JavaScript following arithmetic assignment operations like

**+=, -+, *=, /=, %=**

** **

S.NO | Operator & Description |

1 | += AddandAssignment
It will going to add the right operand to the left operand Ex: x += y is equivalent to y = x+y |

2 | −= SubtractandAssignment
It will going to subtract the right operand to the left operand Ex: x -= y is equivalent to y = x-y |

3 | *= MultiplyandAssignment
It will going to multiple the right operand to the left operand Ex: x *= y is equivalent to y = x*y |

4 | /= DivideandAssignment
It will going to divides the right operand to the left operand Ex: x /= y is equivalent to y = x/y |

5 | %= ModulesandAssignment It will going to modulus the right operand to the left operand
Ex: x %= y is equivalent to y = x%y |

__Javascript Assignment Operators__:-

JavaScript following assignment operations like

**=, ==, === **

S.NO | Operator & Description |

1 | = Assignment
It will Assigns the values from the right side operand to the left side EX:- x=10; |

2 | = = Equal
It will check the two operands are equal or not, so if that operands are equal than condition is true EX:- x=10;y=20; X==y is not true |

3 | === Equal
It will check the two operands are equal the value and equal the type ,then only it will becomes true EX:- x=10; y=”10”; X==y is not true |

__Javascript Conditional Operators__:-

JavaScript following Conditional operations like (? : )

? : Conditional

It will check If Condition is true? Then value X : Otherwise value Y

__Javascript Boolean Operators__:-

JavaScript following Boolean operations like true and false,

Very often, in scripting , you will need a data type values can only have one of two values, like true or false,Yes or No, On or off.

__Javascript Increment & Decrement Operators__:-

JavaScript following Increment & Decrement operations like ++,–

X=10;

++ Increment Increases an integer value by one

Ex: x++ will give 11

— Decrement Decreases an integer value by one

Ex: x– will give 9

__Javascript Bitwise Operators or Javascript Ternary Operators__:-

JavaScript following bitwise or ternary operators like

& BitwiseAND, | BitWiseOR, ^ BitwiseXOR, ~ BitwiseNot, << LeftShift, >> RightShift

Per example variable value X have 2 and variable value Y have 3, then

S.NO | Operator & Description |

1 | & BitwiseAND
It will check a Boolean AND operation on each bit of its integer arguments. Ex: x & y is 2 |

2 | | BitWiseOR
It will check a Boolean OR operation on each bit of its integer arguments. Ex: x | y is 3. |

3 | ^ BitwiseXOR
It will check a Boolean performed OR operation on each bit of its integer arguments. performed OR means that either operand one is true or operand two is true, but not both. Ex: x y is 1. |

4 | ~ BitwiseNot
It will check a unary operator and operates by reversing all the bits in the operand. Ex: y is -4. |

5 | << LeftShift
It will check to moves all the bits value in its first operand to the left by the number of places specified in the second value operand. it returns 1 if the bits are different. Ex: x << 1 is 4. |

6 | >> RightShift
It will check Binary Right Shift Operator. The left operand’s value is moved right by the number of bits specified by the right operand Ex: x s>> 1 is 1. |
