Here is the description of Operators:
An operator is a symbol that represents a specific operation to be performed on one or more operands.
• An operand is a value or a variable on which the operation is performed.
• The combination of an operator and its operand(s) forms an expression.
JavaScript includes various types of operators that allow you to perform operations on variables and values.
Here are some of the key JavaScript operators:
- Arithmetic Operators
- Assignment Operators
- Comparison Operators
- Logical Operators
- Increment/Decrement Operators
- Conditional (Ternary) Operator
- Bitwise Operators
- typeof Operator
Arithmetic Operators:
Arithmetic operators are symbols used to perform basic mathematical operations on operands.

Here’s an example code snippet demonstrating the use of arithmetic operators in JavaScript:
// Addition
var additionResult = 5 + 3;
console.log("Addition Result:", additionResult); // Output: 8
// Subtraction
var subtractionResult = 10 - 4;
console.log("Subtraction Result:", subtractionResult); // Output: 6
// Multiplication
var multiplicationResult = 3 * 7;
console.log("Multiplication Result:", multiplicationResult); // Output: 21
// Division
var divisionResult = 20 / 5;
console.log("Division Result:", divisionResult); // Output: 4
// Modulus (Remainder after division)
var modulusResult = 15 % 4;
console.log("Modulus Result:", modulusResult); // Output: 3
// Exponentiation
var exponentiationResult = 2 ** 3;
console.log("Exponentiation Result:", exponentiationResult); // Output: 8
Assignment Operators:
The assignment operator (=) is used to assign a value to a variable. It assigns the value on its right to the variable on its left.
Here’s an example of JavaScript code demonstrating the usage of assignment operators:
// Assignment Operator
let a = 5; // a is assigned the value 5
// Addition Assignment
let b = 10;
b += 3; // equivalent to: b = b + 3, so b is now 13
// Subtraction Assignment
let c = 8;
c -= 2; // equivalent to: c = c - 2, so c is now 6
// Multiplication Assignment
let d = 4;
d *= 5; // equivalent to: d = d * 5, so d is now 20
// Division Assignment
let e = 15;
e /= 3; // equivalent to: e = e / 3, so e is now 5
// Modulus Assignment
let f = 7;
f %= 3; // equivalent to: f = f % 3, so f is now 1
console.log(a); // Output: 5
console.log(b); // Output: 13
console.log(c); // Output: 6
console.log(d); // Output: 20
console.log(e); // Output: 5
console.log(f); // Output: 1
