JavaScript Operators - Types of Operators in Javascript

JavaScript Operators

The Assignment Operator (=) assigns a value to a variable.

let x = 10;
// Assign the value 5 to x
let x = 5;
// Assign the value 2 to y
let y = 2;
// Assign the value x + y to z:
let z = x + y;

The Addition Operator (+) adds numbers.

let x = 5;
let y = 2;
let z = x + y;
O/P:7

The Multiplication Operator (*) multiplies numbers.

let x = 5;
let y = 2;
let z = x * y;
O/P:10

Types of JavaScript Operators

There are different types of JavaScript operators.

Arithmetic Operators
Assignment Operators
Comparison Operators
Logical Operators
Conditional Operators
Type Operators

JavaScript Arithmetic Operators

Arithmetic Operators are used to perform arithmetic on numbers.

let a = 3;
let x = (100 + 50) * a;
O/P:450

Operator	Description
+	Addition
-	Subtraction
*	Multiplication
**	Exponentiation (ES2016)
/	Division
%	Modulus (Division Remainder)
++	Increment
--	Decrement

JavaScript Assignment Operators

Assignment operators assign values to JavaScript variables.
The Addition Assignment Operator (+=) adds a value to a variable.

let x = 10;
x += 5;

Operator	Example	Same As
=	x = y	x = y
+=	x += y	x = x + y
-=	x -= y	x = x - y
*=	x *= y	x = x * y
/=	x /= y	x = x / y
%=	x %= y	x = x % y
**=	x **= y	x = x ** y

Adding JavaScript Strings Example 1

The + operator can also be used to add (concatenate) strings.

Sample Code

let text1 = "John";
let text2 = "Doe";
let text3 = text1 + " " + text2;

Output

John Doe

Adding JavaScript Strings Example 2

The += assignment operator can also be used to add (concatenate) strings.

Sample Code

let text1 = "What a very ";
text1 += "nice day";

Output

What a very nice day

Adding Strings and Numbers

Adding two numbers, will return the sum, but adding a number and a string will return a string.

Sample Code

let x = 5 + 5;
let y = "5" + 5;
let z = "Hello" + 5;

Output

10
55
Hello5

JavaScript Comparison Operators

==	equal to
===	equal value and equal type
!=	not equal
!==	not equal value or not equal type
>	greater than
<	less than
>=	greater than or equal to
<=	less than or equal to
?	ternary operator

JavaScript Logical Operators

Operator	Description
&&	logical and
\|\|	logical or
!	logical not

JavaScript Type Operators

Operator	Description
typeof	Returns the type of a variable
instanceof	Returns true if an object is an instance of an object type

JavaScript Bitwise Operators

Bit operators work on 32 bits numbers.
Any numeric operand in the operation is converted into a 32 bit number. The result is converted back to a JavaScript number.

Operator	Description	Example	Same as	Result	Decimal
&	AND	5 & 1	0101 & 0001	0001	1
\|	OR	5 \| 1	0101 \| 0001	0101	5
~	NOT	~ 5	~0101	1010	10
^	XOR	5 ^ 1	0101 ^ 0001	0100	4
<<	left shift	5 << 1	0101 << 1	1010	10
>>	right shift	5 >> 1	0101 >> 1	0010	2
>>>	unsigned right shift	5 >>> 1	0101 >>> 1	0010	2
