What are Operators in JavaScript?

Operators in JavaScript are the symbols used in any programming language for any general calculation or operation. Every programming language has operators which can be used while programming. Operators in JavaScript play a major role in creating applications, be it building a small calculator or a big application, it is used everywhere.

JavaScript Operators are the symbols used to perform operations on operands. They are symbolic representation using which several operations are performed. It is used in programs to perform specific operations like mathematical, comparison, etc.

Operators in JavaScript are classified in various types based on their functionalities. Here's an overview of the most commonly used operators -

1. Arithmetic Operators
2. Logical Operators
3. Comparison Operators
4. Assignment Operators
5. Bitwise Operators
6. Ternary Operators
7. Type Operators

We'll discuss the types of operators in the upcoming articles.

Operators are extensively used in real-time applications built with JavaScript. Below given are some examples of operators used in real-time applications.

1. Operators are used in e-commerce applications to perform calculations such as those given in shopping cost, discounts, etc.

For example: Code snippet to calculate the item's price with the quantity required.

let unitPrice = 10;
let quantity = 5;
// Multiplication operator
let totalPrice = unitPrice * quantity;
console.log("The total price is: " + totalPrice);

This example tells you about the multiplication operator in JavaScript the price of the items with its quantity.

2. You can also use operators in gaming applications which uses arithmetic, logical and assignment operator to calculate score, player movements, etc.

For example: Code snippet to execute the moving game objects.

let playerX = 10;
let playerY = 20;
let moveSpeed = 5;
// Addition and subtraction operators
playerX += moveSpeed;
playerY -= moveSpeed;
console.log("Player position: (" + playerX + ", " + playerY + ")");

Usage of arithmetic operators of JavaScript to execute the movement of objects in gaming applications.

3. Operators can also be used in social media applications where comparison and logical operators manage user interactions and data.

For example:To calculate the likes and dislikes of the posts

let postLikes = 50;
let postDislikes = 5;
// Addition and subtraction operators
postLikes += 1;
postDislikes -= 1;
console.log("Likes: " + postLikes + ", Dislikes: " + postDislikes);

This example calclulates the likes and dislikes of the post using the arithmetic operator.

4. Operators can also be used in financial applications which uses arithmetic operators extensively to perform interest rates, loan, and other calculations.

For example: To calculate the interest rate of any given amount.

let principal = 10000;
let rate = 0.05;
let time = 5;
// Multiplication operator
let interest = principal * rate * time;
console.log("Interest: " + interest);

This example calculates the interest rate of the given principal amount using arithmetic operator.

Operators are used extensively in real-time applications to perform a wide range of operations. It performs arithmetic operations to complex data processing and analysis. In this module, we have discussed about the operators, its types and real-time applications. Moving forward, we'll read about the types of operators individually in different sections.
