TypeScript Arithmetic Operators:

Arithmetic operators are used to perform arithmetic operations.

TypeScript Arithmetic Operators List:

Operator	Description	Example
+	Addition	30+20 = 50
–	Subtraction	30-10 = 20
*	Multiplication	10*10 = 100
/	Division	50/10 = 5
Modulus (Remainder)	5
++	Increment	var a=10; a++; Result into a = 11
—	Decrement	var a=10; a–; Result into a = 9

TypeScript Arithmetic Operators Example:

var num1:number = 20;
var num2:number = 4;
var result:number = 0;
 
result = num1 + num2;
console.log("Sum: "+result); 

result = num1 - num2; 
console.log("Difference: "+result);

result = num1*num2;
console.log("Product: "+result);

result = num1/num2;
console.log("Quotient: "+result);
 
result = num
console.log("Remainder: "+result);

num1++ 
console.log("Value of num1 after increment: "+num1);

num2-- 
console.log("Value of num2 after decrement: "+num2);

TypeScript Comparison Operators:

TypeScript comparison operators are used to compare the two operands.

TypeScript Comparison Operators List:

Operator	Description	Example
==	Is equal to	10==30 = false
===	Identical (equal and of same type)	10==40 = false
!=	Not equal to	20!=20 = true
!==	Not Identical	20!==20 = false
>	Greater than	30>10 = true
>=	Greater than or equal to	40>=10 = true
<	Less than	25<10 = false
<=	Less than or equal to	25<=10 = false

TypeScript Comparison Operators Example:

var num1:number = 15;
var num2:number = 17;

console.log("Value of num1: "+num1); 
console.log("Value of num2 :"+num2);
 
var result = num1>num2 
console.log("num1 greater than num2: "+result)

result = num1=num2 
console.log("num1 greater than or equal to  num2: "+result)

result = num1<=num2
console.log("num1 lesser than or equal to num2: "+result)  

result = num1==num2 
console.log("num1 is equal to num2: "+result)  

result = num1!=num2  
console.log("num1 is not equal to num2: "+result)

TypeScript Bitwise Operators:

JavaScript bitwise operators are used to perform bitwise operations on the operands

TypeScript Bitwise Operators List:

Operator	Description	Example
&	Bitwise AND	(10==25 & 20==35) = false
|	Bitwise OR	(20==30 | 20==40) = false
^	Bitwise XOR	(20==30 ^ 30==40) = false
~	Bitwise NOT	(~20) = -20
<<	Bitwise Left Shift	(10<<2) = 40
>>	Bitwise Right Shift	(10>>2) = 2
>>>	Bitwise Right Shift with Zero	(10>>>2) = 2

TypeScript Bitwise Operators Example:

var a:number = 2;   
var b:number = 3;
 
var result; 
     
result = (a & b);     
console.log("(a & b) => ",result);
          
result = (a | b);          
console.log("(a | b) => ",result);  
       
result = (a ^ b);  
console.log("(a ^ b) => ",result);
 
result = (~b); 
console.log("(~b) => ",result);

result = (a << b); 
console.log("(a << b) => ",result); 

result = (a >> b); 
console.log("(a >> b) => ",result);

Typescript Logical Operators:

Typescript logical operators are used to perform logical operations on the operands.

Typescript Logical Operators List:

Operator	Description	Example
&&	Logical AND	(20==40 && 20==30) = false
||	Logical OR	(20==40 || 20==30) = false
!	Logical Not	!(20==30) = true

TypeScript Logical Operators Example:

var avg:number = 20; 
var percentage:number = 90; 

console.log("Value of avg: "+avg+" ,value of percentage: "+percentage);
 
var result:boolean = ((avg>50)&&(percentage>80)); 
console.log("(avg>50)&&(percentage>80): ",result);

var result:boolean = ((avg>50)||(percentage>80)); 
console.log("(avg>50)||(percentage>80): ",result);

var result:boolean=!((avg>50)&&(percentage>80)); 
console.log("!((avg>50)&&(percentage>80)): ",result);

TypeScript Assignment Operators:

TypeScript assignment operators are used to assign the values to the operands.

TypeScript Assignment Operators List:

Operator	Description	Example
=	Assign	a = 10 + 10; Result into a = 20
+=	Add and assign	var a=10; a+=20; Result into a = 30
-=	Subtract and assign	var a=20; a+=10; Result into a = 10
*=	Multiply and assign	var a=10; a*=20; Result into a = 200
/=	Divide and assign	var a=10; a/=2; Result into a = 5
Modulus and assign	var a=10;

TypeScript Assignment Operators Example:

var a:number = 20 
var b:number = 15  

a = b 
console.log("a = b: "+a)

a += b
console.log("a+=b: "+a)

a -= b 
console.log("a-=b: "+a)

a *= b 
console.log("a*=b: "+a)

a /= b 
console.log("a/=b: "+a)    

a
console.log("

Typescript Conditional Operator:

Typescript conditional operator is used as a shortcut for the if statement. It takes three operands. If condition is true, the operator returns the value of expr1 otherwise it returns the value of expr2.

Typescript Conditional Operator Syntax:

condition ? expr1 : expr2

TypeScript Conditional Operator Example:

var num:number = 10; 
var result = num > 0 ?"positive":"negative" ;
console.log(result);

Typescript String Operator:

Typescript string operator refers to (+) which when used with two strings, it appends the second string to the first.

TypeScript String Operator Example:

var msg:string = "Hello "+"jai" 
console.log(msg)

Typescript typeof Operator:

Typescript typeof operator returns the type of object

TypeScript typeof Operator Example:

var name = "Jai";
console.log(typeof name);
