The Operators in Javascript are used to perform mathematical operations in the Javascript Code. Several Operations like concatenation, adding two values, and so on can be achieved using operators.

Different Types of Operators in Javascript by which we can perform various tasks are -

• Assignment Operators
• Arithmetic Operators
• Comparison Operators
• Logical Operators
• Bitwise Operators
• String Operators

Various Javascript operators can perform multiple tasks, in such cases, Javascript is like -

Arithmetic Operators

The operators which can handle mathematical tasks in Javascript are known as Arithmetic Operators. Different Types of Arithmetic Operators are -

Addition (+) - The `Addition operator is used to add two or more numbers and the code for the same is mentioned below -

let a = 1;
let b = 2;
console.log(a+b);
//Output: 3

Subtraction (-) - The Subtraction Operator is used to subtract a value from another. The Code for the same is as follows -

let a = 1; let b = 2; console.log(b-a);
//Output: 1

Multiplication (*) - It is used to multiply two or more values. The code for the same is as follows -

let a = 1; let b = 2; console.log(a*b);
//Output: 2

Division (/) - We can divide two values using the division operation as shown below -

let a = 4; let b = 2; console.log(a/b);
//Output: 2

Exponentiation (**) - It will power the number with the number written next to it as below -

let a = 4; let b = 2; console.log(a**b);
//Output: 16

Modulus (%) - It will return the remainder when two numbers are divided as follows -

let a = 4; let b = 2 console.log(a%b);
//Output: 0

Increment (++) - It is used for incrementing the values as follows -

let a = 3; const b = a++; console.log(a:${a}, b:${b});
// Expected output: "a:4, b:3"

Decrement (--) - It is used to decrease the value as follows -

let a = 3; const b = a--; console.log(a:${a}, b:${b});
// Expected output: "a:2, b:3"

Assignment Operators

The Assignment Operators are used to assign values to the Javascript variables. Different types of Assignment Operators are as follows -

• "=" which can be written as a=b.
• "+=" which can be written as a+=b.
• "-=" which can be written as a-=b.
• "*=" which can be written as a*=b.
• "/=" which can be written as a/=b.
• "%=" which can be written as a%=b.
• "**=" which can be written as a**=b.

A code snippet showing the use of the assignment operators is mentioned below -

let a = 5; a += 5 console.log(a)
//Output: 10

Comparison Operators

The Operators which are used for comparing values are known as Comparison Operators. Various Comparison Operators in Javascript are as follows -

• "=" - Equals
• "===" - Equal value and equal type
• "!=" - Not equal
• "!==" - Not Equal value and not equal type
• ">" - Greater than
• "<" - Less than
• ">=" - Greater than or equal to
• "<=" - Less than or equal to
• "?" - Ternary Operator

The code snippet showing the use of Comparison Operators is as follows -

let a = 5; let b = 7; console.log(a >= b);
//Output: false

String Operators

All the operators mentioned above like Arithmetic Operators, Assignment Operators, can be used with string as mentioned in the code below -

let str_1 = "Hello"; let str_2 = "World"; console.log(str_1+str_2);
//Output: Hello World

##Logical Operators The Operator who performs operations on binary numbers is known as a `Logical Operator`. There are three types of Logical Operators as follows -

• && - Logical AND
- The result will be true if all the inputs are true.
• || - Logical OR
- The result will be true if any of the two inputs is true.
• ! - Logical NOT
- Convert false to true and true to false.

Bitwise Operators

These operators work on bits. The input must be converted to 32 bits binary before applying bitwise operators. Different types of Bitwise Operators are -

• & - AND
• | - OR
• ~ - NOT
• ^ - XOR
• << - Left Shift
• >> - Right Shift
• >>> - unsigned Right Shift

The code snippet showing the implementation of Bitwise Operators is as follows -

let x = 5 & 1; let y = 5 | 1; console.log(x) console.log(y)
//Output: 1 //Output: 5
