# Typescript Bitwise and Assignment Operators explained

#### Bitwise operators

these are to evaluate bit based operations. Sometimes it is required to evaluate bits of integer values, We have to use bitwise operators. There are sevaral operators like in many programming languages. This operator work with 32 bits of an integer
Syntax Operand Operator Operand2
Let assume that Value of A and B are 5 and 10

Operator

Title

Description

Example

&

Bitwise ANd

Evaluates And operation on bits Integers parameters

A & B is 0

|

Bitwise OR

Evaluates Or operation on bits Integers parameters

A | B is 15

^

Bitwise XOR

Evaluates exclusive operation on bits of Integers parameters

A ^ B is 15

~

Bitwise NOT

Not operator on bits of parameter

~A is -6

«

Left Shifts

First shifts left bits of the first opernad by second oeprand times and remaining bits will be filled with zero

A<

>>

Right Shifts

First shifts right bits of the first opernad by second oeprand times and remaining bits will be filled with zero

A»B is 0

Right Shifts with zero

Evaluation is right shift + left Bits shifted replaced with zero

A»>B is 0

Example

``````
var A = 5
var B = 10
console.log(A & B) // returns 0
console.log(A | B) // returns 15
console.log(~A) // returns -6
console.log(A^B) // returns 15
console.log(A<**>B) // returns 0
console.log(A>>>B) // returns 0
**
``````

#### Assignment Operators

Assignment operators do some operations and  assign the value from left to right  values

Syntax

Operand1 Assignment-operator Operand2

Operator

Title

Description

Example

=

Simple assign

Evaluates And operation on bits Integers parameters

a=2 and value of a is 2

+=

Add right operand to left and assign the result to left operand

a+=2 and value of a is equal to a=a+2

-=

Subscrtract and assign

Subtract right operand to left and assign the result to left operand

a-=2 and value of a is equal to a=a+2

*=

Multiply And assign

Multiply right operand with left and assign the result to left operand

a*a=2 is equal to a=a*2

/=

Divide and assign

Divide right operand with left and assign the result to left operand

c/=2 is equal to c=c/2

%=

Modulus And Assign

Divide right operand with left and assign the result of the remainder to left operand

c%=2 is equal to c=c%2

«=

Left Shifts And assign

Perform left shift and result is assigned to left operand

c«=2 is equal to c=c«2 td="“>

>>=

Right Shifts And assign

Perform Right shift and result is assigned to left operand

c»=2 is equal to c=c»2

&=

Bitwise And Assign

Perform Bitwise And and the result is assigned to left operand

c&=2 is equal to c=c&2

^=

Bitwise Exclusive And Assign

Perform Bitwise Exclusive OR and result is assigned to left operand

c^=2 is equal to c=c^2

|=

Bitwise Or And Assign

Perform Bitwise inclusive OR and the result is assigned to left operand

c|=2 is equal to c=c|2

#### Comma Operator

This operator symbol is,(comma). This is used to perform the multiple expressions and return the last expression value. Multiple expression is evaluated from left to right.

Syntax :- (Operand/Expression,Operand2) Example

``````var variable =10;
variable = (--variable, variable);
console.log(variable); // outputs 9

``````
