Arithmetic operators are fundamental components of any programming language, including JavaScript. They allow developers to perform mathematical calculations within their code, enabling the manipulation of numerical data.

While arithmetic operations might seem straightforward, mastering them is crucial for writing efficient and error-free JavaScript programs.

In this guide, we’ll delve into the essential arithmetic operators in JavaScript, providing clear explanations and practical examples to help you level up your programming skills.

Addition Operator (+)

The addition operator, denoted by the plus sign (+), is used to add numbers together in JavaScript. It can also concatenate strings.

let sum = 5 + 3; // sum equals 8
let message = "Hello, " + "world!"; // message equals "Hello, world!"

Subtraction Operator (-)

The subtraction operator, represented by the minus sign (-), subtracts one number from another.

let difference = 10 - 4; // difference equals 6
