JavaScript Operators: The Basics You Need to Know

In the previous blog of this JavaScript series , we learned about Variables and Data Types — how JavaScript stores information. Now the next question is: How do we actually work with those values? That’s where operators come in. Operators allow us to perform calculations, compare values, and create logic in our programs . They are a fundamental part of writing any JavaScript code. In this article, we'll explore the most common operators you will use every day. JavaScript operators can be grouped into several categories such as arithmetic, comparison, logical, and assignment operators. What Are Operators? An operator is a symbol that performs an operation on values or variables. For example: let a = 10 ; let b = 5 ; let result = a + b ; console . log ( result ); Here: + → is an operator a and b → are operands The operator combines values to produce a result . Arithmetic Operators Arithmetic operators are used to perform basic mathematical calculations . Operator Description + Addition -
